The Plasson Pipe Liner 7950 (20mm) is a crucial structural reinforcement component designed to be inserted inside the end of a 20mm metric MDPE (Medium Density Polyethylene) water supply pipe prior to compression fitting assembly. It is widely utilized by plumbing, utility, and agricultural professionals whenever connecting plastic pipes to ensure that the tubing maintains its circular profile and mechanical integrity under clamping force.
 
Manufactured from high-grade, corrosion-resistant stainless steel or durable engineering polymers, this rigid sleeve prevents the polyethylene pipe wall from collapsing inward when the compression nut, split ring, and O-ring seal are tightened down. This structural support is essential for maintaining a firm, permanent grip and preventing the pipe from pulling out of the fitting under operational pressure or soil movement.
 
Engineered for quick, manual insertion on site during pipe preparation, the liner slips smoothly into the bore of the cut pipe end to provide an unyielding backstop for the compression mechanism. Fully compatible with standard metric MDPE systems and rated to support high-pressure applications up to 16 bar, this trade-quality pipe liner ensures absolute joint stability and prevents long-term creep or leakage in critical water supply infrastructure.
