What are threaded pipe fittings?

Threaded joints are one of the most well-known and commonly used methods to connect plumbing systems. Threaded fittings are still used for connection and installation of valves and equipment, although press fittings have superseded a lot of the old inefficiencies.

Types Of Threads In Threaded pipe fittings

BSP threads both parallel or taper are the most common threads in Australia, Other widespread threads used in the fluid-power business are American pipe threads (NPT/NPTF), SAE and Unified threads (UN/UNF), and other thread types. The basic types of threads used in pipe-threaded fittings are as follows:

  1. BSPT (BSP- tapered)
  2. BSPP (BSP- parallel)
  4. UN/UNF

Types of Fittings in Threaded Pipes

Here are some general fittings found with threaded connections:


Barrel unions consist of 3 parts and are good for disconnecting and reconnecting equipment for servicing without damaging the integrity of the fixed pipework. Male-to-female unions, female-to-female unions are available in stainless steel, brass or galvanised iron.


There are different kinds of threaded elbows, as follows:

90° Threaded Elbow: These elbows are utilised for pipe runs that require 90° direction changes.

45° Threaded Elbow: These threaded Elbows aid in the main pipe’s ability to change direction by 45°.


A threaded tee pipe fitting forms a right angle from the main pipe run. Tees are of two types- one is an equal tee, and the other is a reducing tee. The main pipe and branch pipe have a similar size for equal tee. The branch pipe is smaller than the main pipe for a reducing tee.


A dead end or future extension of ends of the pipework are sealed or covered with threaded caps. Therefore, threaded pipe caps are used for sealing.


Threaded bushes help reduce sizes of larger bsp threads to suit individual points, or smaller connection sizes.


Four-way fittings are nothing else but threaded crosses or cross tees. It has three outlet connections and one intake. As a result, three directions are represented by the flow in pipe crosses. 

Which is better- Stainless Steel or Brass Threaded Pipe Fitting?

Both brass and stainless steel are commonly used in industries to join valves or equipment. Stainless steel has its advantages and disadvantages, just like brass threaded fittings. Depending on the purpose of the fittings, you need to choose which material would be the best to opt for. 

Stainless steel corrodes less and looks attractive when installed. With the cost of copper and brass it is often more economic to use stainless steel with its better corrosion resistance.

Frequently Asked Questions

The most frequent application of compression fittings is on plastic pipes. We can supply compression fittings for high pressure stainless steel tubing, but the fittings and specialist tubing are expensive.
Tightening can be done initially by hand tightened with spanners or wrenches. To make sure the threads are correctly aligned, a good technique is to begin by rotating the fitting backwards to align the 2 threads by hand before using tools that may lead to cross-threading. Crossing threads not only makes it more difficult to subsequently align the threads but also increases the chance of stripping the threads.
All threaded joints require sealants to prevent leaks, but also to prevent spalling of stainless to stainless threads. Teflon tape is the most common. we only stock and recommend high body teflon tapes such as yellow for gas, green for Oxygen or grey for all general applications. A quality anaerobic sealant like Titaseal or one of the Loctite range is highly recommended.
It is often suggested to utilise a combination of Teflon tape and a silicone-based joint compound to achieve a thorough and dependable seal on threaded brass fittings. This approach provides an extra layer of assurance to ensure an utterly leak-free joint. Teflon tape acts as a reliable thread sealant, effectively preventing leaks by filling gaps between the threads. When paired with a silicone-based joint compound, the joint's integrity is further reinforced. It enhances the sealing properties and reduces the risk of any potential leaks. By employing this combination method correctly, you can achieve a secure and durable connection on your threaded brass fittings. Copper pipe fittings come in various types, each with different fitting methods to suit different plumbing needs. Here are the four main types of copper pipe fittings and their corresponding fitting methods:

  1. Type K : Type K copper pipe fittings can be joined using various methods, including soldering, compression fittings, push-fit fittings, press-connect fittings, and flare fittings (for flexible pipe applications).

  2. Type L: Type L copper pipe fittings can also be connected using soldering, compression fittings, push-fit fittings, press-connect fittings, and flare fittings (for flexible pipe applications).

  3. Type M : Type M copper pipe fittings can be joined using soldering, compression fittings, push-fit fittings, and press-connect fittings. Flare fittings are not typically used with Type M copper pipe.

  4. DWV (Drain, Waste, and Vent) : DWV copper pipe fittings are primarily used for drain, waste, and vent systems. They are typically joined using soldering or slip-joint methods, depending on the specific application and local building codes.
When selecting the appropriate copper pipe fitting type, it is essential to consider the specific plumbing requirements, local building codes, and the fitting method most suitable for the job. It ensures a secure and leak-free connection that meets the intended application's demands. You can consult with our plumbing professional to determine the most appropriate type of copper pipe fitting for a particular project.
Threading stainless steel pipe requires specialised dies rather than standard pipe dies. Standard dies are not suitable for threading stainless steel due to the material's hardness and unique properties. These special dies are specifically designed to handle the challenges presented by stainless steel, ensuring precise and clean threading.

When working with stainless steel pipes, it is essential to use the appropriate tools and equipment. It ensures efficient and effective threading, resulting in secure and reliable connections.
Poly fittings, also known as polyethylene fittings, do not typically require the use of thread tape. Poly fittings are designed with a tapered thread, which creates a tight seal without the need for additional sealing materials like thread tape. The tapered threads of poly fittings rely on compression and friction to create a secure connection, effectively preventing leaks.

However, it is important to note that the specific manufacturer's instructions and guidelines should always be followed when working with poly fittings. In some cases, thread tape or other sealing methods may be recommended or required for certain applications or unique circumstances. It is always advisable to consult the product documentation or contact the manufacturer directly to ensure the correct installation procedures are followed for poly fittings.
