The Four Types of Europress Pipe Fittings

Since they were first introduced in 1968, Europress pipe fittings have become a popular solution for a wide variety of piping systems throughout the European and international markets. As a leading provider of pipe systems and compressed air equipment, to Australian industries, Air Energy has been a longstanding proponent of the innovative and versatile Europress product range. While all Europress components are designed and built to meet the same exacting standards, the different fittings are made to suit different settings and applications. In this blog, we will outline the four main types of pipe fittings in the Europress range.

Standard Fittings

The standard range of Europress fittings are made from high-quality 316L stainless steel. Unlike other stainless steel piping, many of which require open-flame welding, Europress fittings are simply pressed together to form an airtight seal. This massively reduces the cost and time required for installation – up to ten times faster than traditional instals.

The new range of standard Europress fittings feature the innovative ‘No Leak Solution’. These fittings feature Europress’s unique PressCheck sleeve, a thin, blue coloured plastic collar attached to the outer edge of the o-ring. This plastic collar tears and falls off when two fittings are pressed together, making it easy to identify any sections that have not been securely joined.

This system eliminates the need for grease or oil, making Europress a hygienic solution that is suitable for food processing and pharmaceutical applications.

Supersize Fittings

The Supersize range of Europress fittings feature the same high-quality steel but are designed to suit larger piping systems. They are ideal for systems of 5” and 6” stainless steel pipework.

Gas Fittings

All gas fittings for the Australia/New Zealand market have to conform to the German Standard DVGW VP614 for gas applications. In order to do this, Europress Gas press Fittings are subjected to a special helium test. Once they have passed this test, Europress Gas Fittings are marked with a ‘PN5’ yellow label to indicate they are suitable for use with gas piping applications as well as the distinctive press check sleeve being yellow.

These pipes have a regulatory maximum operating pressure of 5 bar and can operate in temperatures of -20°C to 70°C.

Carbon Steel Fittings

Europress also offers a range of carbon steel pipe fittings and steel tubes. These are typically made from E195 or E235 to conform to Standard EN 10305, and are available from Air Energy with a choice of o-rings for chemical suitability. The carbon steel fittings have distinctive red press check sleeves.

Carbon steel Europress fittings are commonly used in industrial and civil construction applications that don’t require the unique qualities offered by stainless steel fittings. Some of these applications include oil and diesel fuel lines, closed circuit heating and cooling water systems, compressed air and inert gas systems, and closed circuit sprinkler systems.

The Europress™ Press Fit System

1 Traditionally, stainless steel pipes are connected with the use of naked flames. Not only does this increase the risk of accidents in the workplace, but it also requires hot work permits. These, along with gas bottles and hoses, lengthen and make the process more expensive. However, this situation can be avoided with the Europress™ press fit system.

  • Uses crimp fittings instead of naked flames

2 The radial compression creates a waterproof and airtight seal that ensures there are no leakages in the pipework.

  • The geometric compression prevents rotations and other types of movement.
  • Durable and reliable.
  • For trade professionals that often work with tight budgets and deadlines, the Europress™ press fit system provides an effective and efficient alternative.

Since it first emerged in the early 20th Century, stainless steel has become one of the most widely used metals in the world, and today it is indispensable for a wide variety of industries and applications. The team at Air Energy has worked hard to become one of the leading suppliers of stainless steel pipe Australia-wide. In this blog, we’ll look at some of the most popular applications of stainless steel piping.

The Properties of Stainless Steel

Stainless steel is the name given to a family of highly corrosion resistant steel alloys containing at least 10.5% chromium. The addition of chromium creates a microscopic surface film of chromium oxide, which reacts with oxygen and water molecules in the atmosphere to prevent corrosion. Incredibly, this thin outer layer is not just corrosion-resistant, but actually self-repairing; when the surface layer suffers a small scratch or nick, the chromium oxide molecules are reconfigured to “heal” the damaged area.

Grades of Stainless Steel

Of the many different grades of stainless steel available today, 304 and 316 are the most popular. Stainless steel 304 is the most widely used of all steels due to its high corrosion resistance and relatively low cost. Some of its most common uses include storage tanks, fuel and oil pipework, compressed air piping system, fasteners (like nails, screws, and bolts), commercial and domestic kitchens, cooking pots and pans, and tubing. However, this material is subject to pitting corrosion from chloride and saline exposure.

The main difference between Stainless steels 304 and 316 is that 316 contains molybdenum, which further reduces susceptibility to corrosion, especially from saline and chloride. This improved corrosion resistance makes stainless steel 316 a popular choice for use in marine environments, medical equipment, food production, and pharmaceutical industries.

Uses of Stainless Steel

  • Sanitary Tubing

Unlike other metals such as brass and copper, stainless steel will not tarnish and is easy to clean. This makes it the metal of choice for sanitary tubing used in medical equipment and the food and beverage industries.

  • Liquid Natural Gas (LNG)

Natural gas is often converted into liquid for ease for storage and transportation. If the piping used to carry LNG is damaged, expensive leaks can occur. The corrosion resistance and excellent strength of stainless steel means it is less likely to degrade or corrode, reducing the likelihood of a leak.

  • Aerospace Engineering

Stainless steel alloys containing high levels of chromium and nickel offer excellent heat resistance, which is important when designing aircraft. These types of stainless steel are extremely strong and, like other corrosion-resistant metals like aluminium, are able to be welded.

  • Oil & Gas

As the oil and gas industries are forced to push deeper into the earth in their search for fuel, the demands placed on their equipment become increasingly severe. Harsh, corrosive environments mean that engineers have had to find ways to improve the strength and durability of their equipment in order to prevent burst or leaking pipes. Once again, the exceptional strength and corrosion resistance of stainless steel makes it the obvious choice for these tasks.

  • Compressed Air

The excellent corrosion resistance of stainless steel produces a cleaner, more consistent air stream when used in compressed air system. This combined with the thinner wall designs improves the overall efficiency of the system, as well as offering a longer service life.

Stainless steel has long been a preferred material of pipe makers, and its unique anti-corrosive properties make it especially ideal for use with compressed air systems. Air Energy’s reputation for excellence in quality and service has made us one of the leading suppliers of stainless-steel pipe Australia-wide.

But despite its strength and durability, stainless steel is not totally immune from corrosive damage. In this blog, we take a look at some of the different kinds of corrosion that can affect stainless steel, what typically causes them, and what you can do to prevent them.

What Makes Stainless Steel “Stainless?”

A more accurate name for this material would be “highly stain-resistant steel,” but we realise it’s unlikely to catch on. Stainless steel was invented in 1913, when an English metallurgist discovered that he could increase the stain corrosion-resisting properties of low carbon steel by adding at least 12% chromium. The chromium combines with oxygen to create an invisible layer of chrome oxide on the surface of the steel that is called “passive film.” When this layer is scratched, new oxide molecules quickly form to cover the damaged area, effectively making stainless steel a self-repairing metal.


If the damage is severe enough or the atmospheric conditions are poor, the passive film might not be able to regenerate, and corrosion can occur. Of the various kinds of corrosion that can affect stainless steel, pitting is of greatest concern, as it can compromise the structure of the steel. Pitting in stainless steel is caused by the presence of chlorine ions and exacerbated by continuous wetting. This typically occurs on stainless steel pipes that are directly exposed to the sea and is rarely observed inland or that are repeatedly exposed to chlorine based cleaners,


Tea-staining is a brownish discolouration on the surface of stainless steel. This is a cosmetic issue that does not damage the integrity of the steel and generally does not impact its lifetime. Like pitting, it is caused by corrosive particles in the atmosphere, and it is especially common when the steel is in close proximity to salt water and in areas of high humidity.

Avoiding Corrosion

The best way of avoiding corrosion is to use the material that is best suited to the given application and setting. For instance, high-quality stainless-steel pipes such as Europress 316L have the best corrosion resistance for most industry applications. The main difference between 316 and 316L is the amount of carbon that is in the material -316 has .08 Max carbon content while 316L has a .03 Max carbon content. The primary reason for using an L grade of stainless steel is that this will reduce the tendency of the material to crack after welding.

Eurotubi Pressfittings AISI 316 are suitable for use in environments with low salinity, while AISI 316L pipes work well for areas of moderate salinity. The lower carbon content of 316L means the chromium molecules have less opportunity to bond with the carbon and form chromium carbides, leaving more chromium to create the protective passive layer.

While high-quality stainless steel such as 316 or 316L works for low to medium salinity environments, it is not suitable for transportation of saltwater or sea water. For these applications, Cupronickel press fittings are the best choice, as nickel is highly resistant to the kind of crevice corrosion that is frequently seen in high-salinity environments.

Natural salt water is the most common culprit for steel corrosion, but you should also be aware of the other chemicals that come into contact with your pipes. For instance, one customer of ours had an issue with pitting caused by a chlorine-based wash-down disinfectant drying on hot stainless-steel pipes that were heated by the hot water they were conveying.

304 is a cheaper grade and is corrosion resistant but not as effective as 316 grades, it is ideal for fuel & oil piping. 304 is widely used for kitchen equipment, but 316 grades are recommended for harsher industrial environments.

While every part of a compressed air system has an important role to play, from compressed air piping to quick connect couplings, no part will make or break your system like the air compressor itself. The right compressor can provide you with years of trouble free operation while the wrong one can end up costing you an enormous amount of time and money.

In this blog, we look at what you need to consider when choosing the right air compressor for your system.

What Size Compressor Do I Need?

The size of the compressor you choose will depend on three factors; maximum pressure, maximum flow, and demand cycle compressor strength. Maximum pressure refers to the pressure you will need to supply to your pneumatic tools and equipment, and is typically measured in pounds per square inch (psi), bars, or Pascals (Pa). Maximum flow refers to the available air required for your tools or circuit and can be is commonly measured in cubic feet per minute (cfm), litres per second (l/s) or cubic metres per hour (m³/h).

One of the most important factors in selecting piston compressors is to know the output in Free Air Delivery (FAD) which is a real measure of output rather than Displacement which is a theoretic measure. Also consider the duty cycle as piston compressors should not be operating under load more than 60% of the time, whereas screw compressors need to be worked hard to avoid moisture building up in the oil and corroding the screw components.

Positive Displacement Vs. Centrifugal Compressors

Most industrial air compressors are positive displacement compressors. With this type of compressor, the mechanism, usually powered by electricity, compresses the air by reducing its volume. There are many different types of mechanisms that are used to achieve this. Probably the most common type of positive displacement compressor are piston compressors, which can be single-cylinder or multi-cylinder, can achieve pressure of up to 400 bar and are generally the most affordable air compressor pumps. Other popular types of positive displacement pumps include screw compressors and rotary vane compressors.

Centrifugal compressors, sometimes also called dynamic compressors, use a rotating radial impeller to draw air through the machine in much the same way as turbochargers used in the automotive industry.  They are generally used when a high flow rate and high pressure are required on a continuous basis, as with some applications in the chemical and energy production industries.

Beyond this, there are variants of stationary, transportable, and portable compressors. As the names suggest, stationary compressors are not intended to be moved once they have been installed and are very powerful, while portable compressors can be moved but are generally not intended for regular, heavy use. Transportable compressors fall somewhere in between. They usually feature a combustion engine and include a skid base designed to allow movement with a forklift or pallet truck.

Other Types of Air Compressors

Other variations of air compressors include: silenced compressors, intended to provide powerful performance with considerably reduced noise; variable speed drive (VSD) compressors, which minimise unnecessary energy usage to keep efficiency high and costs low; and oil free compressors, which are provide clean compressed air and are favoured for being more environmentally friendly than other types of compressors.

Since 1993, Air Energy has been supplying our clients with a premium range of specialised compressed air equipment, and aluminium, HDPE or stainless-steel pipes Australia wide. Despite its ubiquity as an energy source in domestic and industrial settings, most people know little about compressed air; how it works, its practical applications, and how it compares to other energy sources for cost and efficiency.

This quick guide is intended to answer some of those questions and give you a basic understanding of compressed air.

What is Compressed Air and How Does it Work?

Compressed air is created when air is forced into a pressure vessel using an electrically or diesel powered air compressor and is stored at a pressure greater than atmospheric pressure. The compressed air is then stored until it is needed and is released as pneumatic energy.

What are the Practical Applications of Compressed Air?

When released at the point of use, compressed air is converted into pneumatic energy that can be used as a power source for any number of mechanisms. Spray painting and various forms of sand blasting use compressed air, and pneumatic energy is an especially popular choice in automated industrial processes, where it can be used to move items through multiple production processes. It is well suited to mechanisms that perform repetitive actions at great force, such as industrial drills and jackhammers and pneumatic tools are much lighter than electric ones, saving OH&S issues and operator fatigue. Pneumatic energy is also used in car and truck braking systems.

What Are the Benefits of Compressed Air?

One of the main benefits of using compressed air system is that, unlike other energy sources such as oil, air itself cannot be depleted, as a limitless amount exists in our atmosphere.

The machinery used in pneumatic systems is also highly durable when compared with other systems. The absence of corrosive elements such as oil paired with the smooth, low impact movements characteristic of pneumatic systems means they are not subject to the same wear and tear. This means lower maintenance costs and remarkable longevity.

Finally, pressurised air can be released back into the atmosphere with no negative consequences. The benefits here are two-fold: firstly, this makes compressed air one of the most environmentally friendly sources of energy; and secondly, it avoids the exorbitant costs involved in the processing and disposal of waste matter associated with other energy sources.

How Efficient/Expensive is Compressed Air?

As explained in the previous section, compressed air has a number of advantages over other energy sources when it comes to cost, but this doesn’t mean that it will be the cheapest option for every situation. Electricity is required to power the machinery that produces compressed air; the greater the pressure and the volume of air required, the more electricity will be needed, and therefore the greater the cost.

However, many processes do not require air to be compressed to the maximum pressure the compressor is capable of producing. Knowing the appropriate volume and pressure required for a given task can greatly reduce the costs of running a compressed air system.

Do Compressed Air Systems Leak?

Even a small hole in the compressed air system can lead to leakage, and those leaks can result in significant losses. Finding and repairing the source of a leak can be time-consuming but very cost effective, and it is for this reason that we suggest a proactive approach to avoiding leakage rather than a reactive one.

Investing in high quality system components and using the advice of specialists when creating and maintaining your compressed air system is the best way to avoid unnecessary costs associated with leakage.

Compressed air systems have a number of advantages over electrical, hydraulic, and other kinds of systems commonly used in manufacturing industries. 240 volt electric powered tools and equipment are a well-documented and known OH&S issue, as well as being heavier due to the inherent design of electric motors powers them. Hydraulic power, no matter how well made regularly is associated with messy oil leaks and the hoses are stiff and cumbersome compared to compressed air hoses. Battery powered tools although much improved on earlier models lack the power available with pneumatics and need constant recharging of the limited lifespan of the batteries.

Air Energy supplies complete compressed air systems along with proven high-quality parts including polymer, aluminium, or stainless-steel pipes Australia-wide. In order to bring our customers, the best possible products and give advice they can count on, we draw on our years of experience designing and delivering compressed air systems to the broadest range of diverse industries. In this blog, we use that same experience to offer you some of our top tips for an optimal compressed air system

1. Use the Correct Size of Feeder Pipe

The feeder pipe as the name implies connects the compressor equipment to the ring main and is the main artery of all the compressed air used in your system. If the feeder pipe is too narrow, the airflow will be restricted, resulting in pressure drop and a less efficient overall system. You should always use a feeder pipe that is one size larger than the ring main to avoid airflow restriction

2. Minimise Elbows

You should design your compressed air system to feature as many straight lengths of pipe as possible and keep the number of elbows to the bare minimum, as each elbow results in a pressure drop equivalent to an additional 1-3 metres of straight pipe. Wherever possible, use radius bends and generally endeavour to make your system as straight as it can be. Balancing that is the requirement to allow for pipe expansion and contraction. As a rule-of-thumb 30 metres is regarded as the maximum straight length between expansion/contraction points.

3. Reduce and Manage Contamination

While compressed air systems are clean and dry compared to other types of systems, they can still become contaminated, which leads to corrosion, decreased efficiency, and the need for frequent maintenance and repair. The first step to avoid this problem is ensuring there is minimal contamination in the air supply. As compressed air is typically 8 bar, that means 8 x the contaminants in the surrounding air is concentrated in each volume of compressed air. Choose a location for your system that is as free of moisture and other pollutants as possible and install an air filtration system.

4. Monitor and Address Leakage

There’s a reason we use the term “airtight” to describe something that is totally secure and without fault; compressed air doesn’t require a lot of room to escape, and even a tiny leak can lead to a massively underperforming system. It’s important to locate and fix leaks as quickly as possible, although unfortunately, there are often no external signs of such damage; a leak generally needs to be significantly advanced before you are able to hear it. The best way to avoid this is to start with high-quality pipes and fittings installed by experienced and reputable technicians.

5. Use High-Quality Pipes and Fittings

Leading on from our previous point, using the best quality materials will reduce the likelihood of faults and increase efficiency from the get-go. Conduct thorough research before choosing a supplier/technician and spend plenty of time talking to them to make sure they understand the requirements of your system. They should be able to explain in simple terms why a particular material or product is the best choice for your application.

6. Plan for Expansion

When you are designing your compressed air system, take the time to think about whether it will likely need to be expanded at some point in the future. If you do eventually need to expand, it will be much easier, faster, and more affordable if this possibility was incorporated into your initial design.

Our team at Air Energy loves a challenge, and our willingness to go above and beyond to bring our customers world-standard products has made us a leading supplier of compressed air systems, fittings, and a variety of synthetic and stainless steel pipe Australia wide. As we move towards the phasing out of fossil fuels in favor of renewable energy sources, the next decade is set to be an exciting and challenging time for us and the HVAC industry as a whole.

The most significant and pressing goal currently in place is the stated aim of the European Parliament to bring about a 55% reduction in carbon emissions by 2030, with the end goal of reaching 0 carbon emissions by 2050. In order to make this happen, we need to explore all the renewable energy sources at our disposal. One of the most promising options currently on the table is thermal solar power. In this blog, we look at how thermal solar power works, its benefits for the HVAC industry, and why steel pressfittings offer the best system to facilitate the transition.

Solar Thermal Power Today

Solar power has long been considered one of the most efficient, cost-effective, and truly green alternative energy sources. The modern solar panel was invented in 1958, and over the following decades, solar power technology spread around the world. Today, it is commonly used for many industrial and residential applications.

Over the last two decades, the technology used to generate and distribute solar power has made huge strides, and the cost of solar panels has dropped significantly while their efficiency has improved and the list of applications to which they are suited has grown. Thermal solar power was previously limited to heating a household’s water supply, but today it used to fulfil many different functions. Through the use of specialised chemicals and inverter cooling technology, solar thermal power can now be effectively used to cool as well as heat buildings.

With the sun providing a virtually limitless supply of energy, thermal solar power will be able to augment and then entirely usurp traditional energy sources between now and 2030.

Why Steel Pressfittings?

The pipes in thermal solar energy systems are required to transport fluids at extremely high temperatures, making them subject to constant thermal expansion. This makes them unsuitable for use with copper pipes, which will deteriorate quickly. Stainless steel is much better suited to withstand thermal expansion and is generally more durable than copper and other materials. Properly maintained, a stainless steel system can last many decades with no serious malfunction.

Pressfitting systems are fast and easy to assemble, and unlike other types of systems that require welding, they do not use an open flame. This is especially beneficial for solar thermal power systems, which often carry highly flammable fluids. Our Eurotubi pressfittings are available in a wide variety of sizes and with differing thread and nut configurations. The right component will also depend on the maximum temperature of the system and whether there is steam present.

At Air Energy, we are committed to bringing our customers the latest, most innovative range of pipes and fittings for HVAC and compressed air systems available anywhere in the HVAC industry. As governments and industries around the world move towards more renewable models, we endeavor to stay on top of advancing technology as it happens. The two main goal posts set by the European Parliament for the prevention of global warming are 2030 and 2050. By 2030, they aim to reduce carbon emissions by 55%; by 2050, they aim to use no fossil fuels whatsoever. We think this is not just admirable, but, with the right combination of ingenuity and commitment, actually achievable,

A big part of staying ahead of the curve is being able to envision what the next stage of development might look like. Traditionally, a huge amount of global energy use has been consumed by HVAC systems. With the world population growing rapidly and ever greater demands being placed on the energy supplies of our towns and cities, engineers and planners have been looking at how they can continue to provide heating, ventilation, and cooling while reducing their carbon footprint. 

HVAC Systems in Smart Cities

“Smart City” is a term used to describe urban areas where there is a high level of interconnectedness between infrastructure, transport, energy supply, and other elements of the urban environment. Part of the idea is to increase energy efficiency with the primary goal of greatly improved environmental sustainability. In the Smart City, for example, if one building is experiencing excess heat, the underlying smart system would be able to harness that heat energy and transfer it to another building.

In order for this to happen, all systems would need to be interconnected at the data level and would use highly sophisticated fiber optics technology and Smart Metres in place of the flow metres and pressure gauges that are currently standard for these systems. Currently, pressure gauges need to be placed at various points throughout the HVAC system to accurately monitor the status of the various processes and equipment. Fiber optic cables allow large amounts of complex data to be transmitted at high speeds, meaning they would be capable of communicating information about the temperature, pressure, and any faults in the systems to the mainframe.

How Press-Fitting Pipes Fit in

The unique Europress press-fitting system is already making HVAC systems more efficient and sustainable, and that same technology will serve to optimise the systems in Smart Cities. Built from high quality steel, Europress pipe fittings are fast and easy to install, and are particularly well suited to use with sophisticated measuring equipment. 

The unique O-ring coloured sleeve system employed by Europress makes it easy to identify potential leaks during the installation process. When the fittings are properly attached, the coloured, plastic sleeve on the end of the pipe fitting falls away. This means technicians can spot any faulty joins before the system is turned on.

In our previous blog, we discussed how to choose the right material for your industrial piping system. We took a look at the main varieties of material used in industrial piping, describing the benefits and limitations of each and touching on their most suitable applications. This month, we’re throwing a spotlight on stainless steel. We’ll discuss the advantages of stainless steel as a material and look at some of the component parts of stainless steel compressed air systems. In particular, we will focus on stainless steel press fittings and what it is that makes these so popular for use in compressed air systems.

What Makes Stainless Steel So Special?

Stainless Steel is an umbrella term applied to corrosion-resistant steel alloys containing 10.5% or more chromium. Their high resistance to corrosion is due to a thin but highly protective layer of chromium-rich oxide film that coats the outer surface. What is remarkable about this layer of oxide is that, in the presence of oxygen, it is actually self-repairing. This means that minor damage caused by abrasion or cutting is quickly repaired. This same layer of oxide means that stainless steel is also highly resistant to rust.

Stainless Steel System Fittings

In addition to the pipes themselves, Air Energy offers an extensive range of innovative No Leak Solution press fittings. These fittings feature a thin, plastic film fitted to the outside of the o-ring. This plastic film tears and falls away only once the fitting has been securely pressed into place. This means that any faulty connections will be easily identified during the installation process.

The Benefits of Stainless Steel Press Fittings for Compressed Air Systems 

Stainless steel pipes can be much thinner than other materials, such as aluminum, while still being highly durable and reliable. When used as part of a press fitting system, they are also much easier and quicker to install, resulting in significant savings in time and labor. For these reasons, stainless steel systems tend to be much more affordable than aluminium piping systems to buy and install.


Besides the initial costs of your compressed air system, the long-term operation and maintenance costs will be one of your key considerations. The unique, rust- and corrosion-resistant properties of stainless steel mean that it is highly durable, although regularly scheduled maintenance is always recommended to catch small areas of degradation before they begin to affect functionality. 


Air Energy’s unique No-Leak Solution press fittings result in less of the compressed air leaking out of your piping system. This translates to a more efficient, less costly, more eco-friendly compressed air system. Not only do our press fittings prevent leakage of compressed air; the secure connections also mean that there is less opportunity for grease, moisture, and dust particles to enter the system, all of which can hasten wear-and-tear and lead to deterioration of the pipes.
