The FloPlast 25mm Compression Coupling is an essential plumbing component designed for professional contractors and DIY enthusiasts who require a reliable connection for 25mm MDPE cold water pipes. It offers the key benefit of rapid, leak-free installation without the need for specialized tools, making it ideal for both above and below-ground service lines. While highly durable and pressure-resistant, users should ensure the pipe ends are cut square and deburred to prevent connection failures, as improper preparation remains the primary cause of joint issues.

No, this compression coupling is specifically designed for cold water service applications.
No, the fitting is designed to be tightened by hand, though a pipe cutter is recommended for a square end.
Yes, it is fully approved for both above and below-ground installations.
The fitting is rated for pressure resistance up to 48 bars.
Yes, it is fully compliant with all relevant UK water bylaws.
While technically possible, it is recommended to use new components for critical water connections to ensure the integrity of the O-ring and grip ring.
Ensure the pipe is pushed fully into the fitting body and that the pipe end was cut square and deburred.
Check that the pipe is properly aligned with the coupling and that there is no debris in the threads of the nut or body.
Verify that the pipe is inserted deep enough and the grip ring has engaged properly when the nut is tightened.
To install the coupling, first ensure the MDPE pipe is cut cleanly and square. Remove any rough edges or burrs from the pipe end, as these can damage the internal O-ring seal. Slide the nut and grip ring onto the pipe, insert the pipe fully into the coupling body, and hand-tighten the nut firmly.
Compatibility is strictly limited to 25mm MDPE pipe; do not attempt to use this fitting with imperial-sized PVC or other dissimilar materials. For maintenance, once installed, it is recommended to monitor the joint during the first few days of pressurization. No regular lubrication is required, and the coupling is designed to remain maintenance-free for the lifespan of the piping system.
