This 25mm Compression Fit MDPE DZR Pipe Liner (Insert) is engineered to reinforce the internal wall of 25mm medium-density polyethylene (MDPE) service pipes during compression jointing.
 
Manufactured from high-grade Dezincification-Resistant (DZR) brass, it prevents the plastic pipe from collapsing or deforming under compression force, maintaining the structural integrity of the joint. Essential for both underground water supply mains and above-ground plumbing systems, it guarantees a continuous, leak-free, and high-pressure seal across all standard 25mm MDPE fittings.
