What is a coupler in plumbing?
A coupler, also known as a coupling, is a plumbing fitting used to connect two sections of pipe together in a straight line. Couplers are available in different sizes and materials to suit different types of pipework and plumbing systems.
They provide a secure connection between two pipes, making them useful when installing new pipework, extending an existing system or repairing damaged sections.
What is a plumbing coupling used for?
A plumbing coupling is primarily used to join two pipes together. Depending on the type of coupling, it can be used with different pipe materials, sizes and installation methods.
Common uses include:
- Joining two lengths of pipe
- Extending existing pipework
- Repairing damaged sections of pipe
- Connecting different sections of a plumbing system
- Making secure, leak-resistant pipe connections
Where are plumbing couplers used?
Couplers can be used across a range of domestic, commercial and industrial plumbing applications. The correct type depends on the pipe material, connection size and system requirements.
They can be found in applications including:
- Domestic water supply
- Central heating systems
- Plumbing installations
- Drainage systems
- Commercial pipework
- Repair and maintenance work
What types of plumbing couplers are available?
There are several types of coupler and coupling available, depending on the application and pipework being connected.
For example, end feed couplers are commonly used with copper pipe and soldered connections, while other couplings are designed for compression, push-fit or threaded connections.
Couplers are also available in different sizes, including common plumbing sizes such as 10mm, 15mm, 22mm and 28mm.
How do I choose the right plumbing coupler?
When choosing a coupler, check the following:
- Pipe size: Make sure the coupling matches the diameter of the pipe.
- Pipe material: Choose a fitting designed for the type of pipe being connected.
- Connection type: Check whether you need solder, compression, push-fit or another connection method.
- Application: Consider whether the fitting is being used for water supply, heating, drainage or another application.
- System requirements: Check pressure, temperature and manufacturer requirements where applicable.
