PLASS4 Universal Adapter Coupling 20 27mm to 25mm

The Plasson Plass4 Universal Coupling is a compression fitting designed to join metric polyethylene (MDPE) to a variety of pipe materials. This 25mm x 20mm to 27mm coupling comes with two split rings, seals, and nuts, and is intended for quick, tool-free assembly. It features a polypropylene body for improved impact strength and stress resistance and carries a PN16 pressure rating. The coupling is suitable for fitting MDPE to metals and plastics such as imperial polyethylene, copper, lead, galvanised steel, PVCu, and poly-york, with the goal of enabling straightforward repairs and long service life. While it supports a wide range of sizes (15mm to 50mm with a few fitting sizes), it is not intended for hot water applications, and users should test suitability in areas with aggressive chemical exposure where necessary.
