Product Information
Full details
The Primaflow 22mm compression coupling is designed for professional plumbers and DIY enthusiasts who need a reliable, heat-free method to join two 22mm pipe lengths. Its primary benefit is the elimination of torches, flames, and solder, which simplifies installation and increases safety in sensitive areas, though users should note that the fitting relies entirely on correct torque application to ensure a leak-free seal.

FAQs
Can I use this on plastic pipe?
This compression coupling is designed for use with copper pipe. If using on certain types of plastic, a suitable pipe insert is required to maintain pipe rigidity.
Is this coupling reusable?
Yes, compression fittings can be reused, though it is recommended to replace the brass olive with a new one to ensure a reliable seal.
Does it need PTFE tape?
While the compression olive creates the seal, a small amount of PTFE tape on the threads can sometimes assist in smoother assembly.
What is the maximum pressure this fitting handles?
It adheres to BS EN1254 standards, which are suitable for standard domestic water supply pressures.
Can I use this in an area I cannot access later?
It is always best practice to ensure plumbing joints remain accessible for inspection, though compression fittings are generally very reliable when installed correctly.
Troubleshooting
Joint is leaking after installation
Check if the pipe was cut square and the end is free of burrs. Tighten the nut slightly more until the leak stops.
Nut is difficult to turn
Ensure the threads are clean and free of debris. Use a small amount of plumbers' lubricant or PTFE tape on the threads if they are stiff.
Olive will not compress
Ensure the pipe is pushed fully into the fitting. If the olive is damaged or deformed, replace it with a new 22mm olive.
Pros and Cons
Pros
- No soldering or open flames required
- Suitable for both professional and DIY plumbing projects
- WRAS approved for safe use with drinking water
- Easy to disassemble for maintenance or pipe replacement
Cons
- Requires proper tightening force to prevent leaks
- Not suitable for applications involving high vibration
- Requires a clean, burr-free pipe end to seal correctly
Setup, Compatibility & Care
Compatibility is straightforward; this fitting is designed specifically for 22mm OD (outside diameter) pipework. Ensure that you are not using this fitting on pipework with deep scratches, as the olive will not be able to form a proper seal. When tightening, do not overtighten, as this can crush or deform the olive, leading to leaks. Periodic maintenance involves checking the joints for any signs of weeping or moisture. If a joint begins to leak, simply cleaning the connection and tightening the nut slightly is often enough to restore the seal.
