This 20mm Compression Fit MDPE DZR Pipe Liner (Insert) is designed to reinforce the inner wall of 20mm medium-density polyethylene (MDPE) service pipes during compression jointing.
 
Manufactured from Dezincification-Resistant (DZR) brass, it prevents the plastic pipe wall from crushing or deforming when tightening the compression fitting, ensuring a long-lasting, leak-free, and pressure-tight seal. Crucial for both underground potable water supplies and above-ground mains installations, it ensures structural integrity and compliance with standard MDPE plumbing systems.
