The Plasson Pipe Liner (20mm) is an essential component for professionals and DIY enthusiasts installing or maintaining 20mm metric MDPE pipe systems. Designed to ensure maximum joint integrity, this liner reinforces the pipe wall to maintain a secure, watertight seal while meeting stringent drinking water safety standards. While it is highly effective at compensating for pipe ovality, it must be matched precisely with the correct outer diameter of the pipe to ensure long-term reliability in water distribution networks.

While not always strictly required by every fitting manufacturer, it is highly recommended to use a liner to guarantee joint integrity, especially for potable water lines.
No, this liner is specifically engineered for metric MDPE (Medium Density Polyethylene) pipe dimensions.
No, the liner is made from materials designed to resist corrosion in water distribution environments.
This liner is rated for 16 Bar, which matches the standard rating for most industrial and residential MDPE pipe systems.
No, this is designed for 20mm metric pipe. Imperial and metric pipe sizes are not interchangeable.
Ensure the pipe end is perfectly round and free of external debris. Check that the compression nut on the fitting is fully unscrewed to allow the grab ring to expand.
Verify that the liner is fully seated inside the pipe and that the compression fitting is tightened to the recommended torque. Check that the pipe itself is not scratched or scored at the sealing point.
To install, ensure the pipe end is cut square and is free from burrs or debris. Slide the liner fully into the end of the 20mm MDPE pipe until it is flush. Proceed to attach your standard 20mm compression fitting over the pipe end. Always ensure that the pipe is compatible with the 16 Bar rating of the liner. No specific maintenance is required once installed, as the liner remains permanently inside the pipe joint. Avoid using lubricants that may degrade the MDPE material; clean water or silicone-based soap is sufficient if a small amount of assistance is needed during insertion.
