Product Information
Full details
The Plumbright Straight Coupling - 22mm is designed for plumbers and DIY enthusiasts needing a reliable connection for hot and cold-water supply lines, particularly in heating systems. Its primary benefit is a durable, long-lasting, and secure connection thanks to its high-quality brass construction and pressure rating. A potential caveat is that its specific 22mm size limits its application to compatible pipe sizes.

FAQs
What is the maximum pressure this coupling can handle?
The Plumbright Straight Coupling is tested to bear pressures up to 16 bar.
Can this coupling be used for gas lines?
No, this fitting is designed and tested for water supplies only, not for gas applications.
What type of pipe can I use with this coupling?
It is suitable for copper, brass, and certain types of plastic pipes designed for compression fittings. Always ensure compatibility with the specific pipe material.
Do I need any special tools to install this?
You will need two wrenches (e.g., pipe wrenches or adjustable spanners) to tighten the compression nuts securely.
Is this coupling suitable for underground use?
While durable, compression fittings are generally recommended for above-ground use or where accessible for inspection. For underground applications, other jointing methods might be more appropriate.
How do I prevent leaks with this type of fitting?
Ensure pipe ends are clean, cut square, and de-burred. Insert the pipe fully into the fitting and tighten the compression nuts evenly and sufficiently with two wrenches.
What is the warranty period for this product?
Please refer to the product packaging or Plumbright's official documentation for specific warranty information.
Troubleshooting
Leak at the connection
Ensure pipe ends are clean and de-burred. Check that the pipe is fully inserted into the coupling. Tighten the compression nuts further, using two wrenches to prevent the fitting from twisting. If the leak persists, consider replacing the fitting and the olive (if applicable).
Difficulty tightening the nuts
Ensure the threads on the coupling and nuts are clean and free from debris. Do not force the nuts; if resistance is too high, check for cross-threading or damaged threads.
Fitting does not seem secure
Verify that the correct size pipe (22mm) is being used and that it is fully seated within the fitting. Ensure adequate tightening of the compression nuts with appropriate tools.
Pros and Cons
Pros
- Durable and long-lasting due to brass material.
- Secure and reliable connection suitable for potable water.
- Can be used in heating systems for both hot and cold supplies.
- High pressure resistance offers peace of mind.
- Easy to install with standard tools.
Cons
- Specific 22mm size may not fit all plumbing configurations.
- Requires clean pipe ends for optimal sealing.
- Compression fittings may require re-tightening over time in some applications.
- Brass can be susceptible to dezincification in aggressive water conditions.
- Not suitable for above-ground applications where it may be exposed to impact.
Setup, Compatibility & Care
Setup:
- Ensure the ends of the two 22mm pipes to be joined are clean, smooth, and free from burrs.
- Unscrew the compression nuts from the coupling.
- Slide the compression nuts onto one of the pipes.
- Place the coupling onto the end of one pipe, ensuring it is fully seated.
- Insert the second pipe into the other end of the coupling.
- Slide the compression nuts forward and tighten them hand-tight onto the coupling body.
- Use two wrenches to tighten the nuts further. One wrench holds the coupling body steady, while the other tightens the nut. Tighten until a secure fit is achieved, but avoid over-tightening which can damage the pipe or fitting.
Compatibility:
- Pipe Size: Exclusively for use with 22mm diameter pipes.
- Material: Compatible with copper, brass, and certain plastic pipes (ensure plastic pipe is suitable for compression fittings and potentially has an insert).
- Application: Suitable for hot and cold-water supplies, including central heating systems.
Care:
- This fitting is designed for permanent installation and requires no ongoing maintenance under normal operating conditions.
- Periodically check for any signs of leakage around the connection points, especially if there have been significant temperature or pressure fluctuations.
- Avoid using abrasive cleaners on the exterior; a damp cloth is sufficient for cleaning.
