Compression Fittings Copper Pipe

Compression fittings are vital in plumbing systems as they serve as couplings to join tubes or smaller flow-diameter pipes. Compression fittings are typically constructed from brass, copper, or stainless steel and provide a versatile solution for connecting PVC, nylon, plastic, or copper tubing.

Their adaptability extends to various plumbing projects, spanning domestic, commercial, and industrial applications, encompassing water mains and hydraulic pumping systems. These fittings derive their name from how they combine pipes through compression. They are known by various terms, including:

  • Compression joints.
  • Compression pipe fittings.
  • Compression nuts
  • Compression couplings
  • Plumbing compression fittings
  • Compression-type fittings.

Compression “O” Ring Fittings

For PP mechanical compression fittings to comply with AS/ NZS 4129 requirements, it is normally considered necessary to provide reinforcement to female threads larger than 25mm. This reinforcement should also be corrosion-resistant and is normally provided in the form of a stainless-steel ring. Threaded outlets larger than 50mm should be avoided. The use of PTFE (Teflon) tape is solely recommended for all fittings with plastic thread.

Quality Certifications

These fittings are manufactured under a certified quality system, ISO 9001:2008, which has been approved by CCC and lQNet. The complete range of mechanical compression fittings have been tested and approved by leading certification agencies; they have Australian Watermark approval and comply with AS/NZS 4129:2008 and NATA accredited Australian Water Quality Centre as well as internationally recognised DVGW (D), KIWA (NL), WRAS (GB), SlI (IL), BV (AUS) and many others worldwide. Furthermore, the fittings are endorsed with product certifications on all related standards, such as ISO 14236, EN 12201 & DIN 8076.

Projected Life Expectancy

Based on the information available and the successful performance under the nominated test procedures, the design life expectancy is rated at 50 years before replacement or major repair. This rating is only a general guide to life expectancy. It may increase or decrease depending on the quality of the installation, system operation and environmental conditions and other geographical and site-specific factors.

Operating Temperature

The fittings are not to be used in hot water, although they withstand the same temperature as the polyethylene pipe. The fittings withstand sub-zero temperatures.

The pressure rating has to be adjusted, as shown in the figure below if the fittings are to be used in higher temperatures.

What are Compression Fittings Used For?

Compression fittings serve as essential components in plumbing systems. They facilitate the connection of copper or plastic tubing and pipework to one another or threaded components like valves. Their simplicity of use and removal makes them an ideal choice for situations where soldering is impractical due to limited space or fire risk.

Beyond plumbing applications, compression fittings find utility in gas installations and hydraulic equipment, serving the needs of industrial engineers. Moreover, while primarily designed for professional projects in plumbing and engineering, compression fittings are also suitable for various DIY applications, such as sink and shower unit pipes, as they eliminate the need for soldering or heat during installation.

How to Use Compression Fittings for Copper Pipe?

Compression fittings are widely used in plumbing systems to establish detachable connections on rigid and flexible copper pipes and tubing. These fittings are commonly employed on water shutoff valves, also known as stop valves, which are commonly found in faucets and toilet water supply pipes.

Additionally, compression union fittings enable joining two pipes in a straight line. By providing a convenient and straightforward installation method, compression fittings serve as an alternative to traditional soldered plumbing connections.

At Air Energy, we stock and supply compression fittings for copper pipes to ensure a leak-free installation. We use brass and copper to make an excellent tool for joining copper pipes with compression fittings. Contact us to discuss your needs.

How Does a Compression Fitting Work?

Compression fittings are designed with a straightforward structure that makes them easy to use. Typically, they comprise three essential components:

  • A tapered nut with threading.
  • A slim brass ring known as a ‘ferrule,’ or an ‘olive’.
  • A tapered insert that forms the main body of the fitting.

The compression fitting operates by tightening the nut, which applies pressure onto the olive. As a result, the barrel-shaped olive ring compresses onto the outer diameter of the pipe, effectively creating a secure and tight seal. This simple yet effective mechanism ensures a reliable connection between the fitting and the pipe..

Compression Fittings Copper Pipe

Several types of pipe compression fittings are available to cater to various plumbing needs. Here are some common types:

  1. Compression Coupling : This type of fitting is used to connect two pipes in a straight line. It comprises a compression nut, an olive or ferrule, and a tapered insert.
  2. Compression Elbow : A compression elbow fitting allows for a change in direction in a plumbing system. It is available in different angles, such as 90 degrees or 45 degrees, to accommodate specific plumbing configurations.
  3. Compression Tee : Compression tees are used to create a branch connection in a plumbing system. They have three openings, allowing for the joining of three pipes together.
  4. Compression Union : Compression unions are employed to disconnect and reconnect pipes easily. They consist of two compression nuts and two olives or ferrules, enabling a secure and removable connection.
  5. Compression Stop Valve : These fittings are commonly found on water shutoff valves. They have a compression nut that compresses the olive onto the pipe, creating a watertight seal when the valve is closed.
  6. Compression Reducer : Compression reducers are used to connect pipes of different diameters. They have different-sized openings on each end to facilitate the transition between varying-sized pipes.
It's important to note that the availability of specific compression fittings may vary depending on the pipe material and regional plumbing standards.
Compression fittings are widely accepted and commonly used in the plumbing industry. They provide a safe and secure method for connecting copper pipes without the need for heat. It makes them particularly popular among DIY enthusiasts. These fittings are essential for ensuring watertight connections and are utilised in various applications, including valves, tees, connectors, and other plumbing utilities. Their reliability and ease of use make compression fittings a trusted choice for professionals and homeowners. It offers a convenient solution for joining pipes and ensures the integrity of plumbing systems.
When working with copper pipe compression fittings, there are a few general rules of thumb to keep in mind:

  • Use the Right Size :Ensure that you are using the correct size of compression fitting for your copper pipe. The fitting and the pipe should have matching outer diameters to create a proper seal.
  • Clean and Deburr the Pipe : Before installing a compression fitting, ensure the copper pipe's end is clean and free from any debris or burrs. Use a deburring tool or sandpaper to remove any rough edges.
  • Cut the Pipe Squarely : Cut the copper pipe squarely to achieve a proper fit is crucial. Use a tubing cutter to make a clean and perpendicular cut, ensuring that the end of the pipe is smooth and even.
  • Apply Proper Torque : When tightening the compression nut, use a wrench to apply sufficient torque. It's important not to overtighten, as this can damage the fitting or cause leaks. Follow the manufacturer's recommendations for the recommended torque value.
  • Test for Leaks : Check for leaks by turning on the water supply after installation. Inspect the connection and ensure there are no visible signs of leakage. If there is a leak, tighten the compression nut slightly until the leak stops.
