Polyplumb Mdpe Adaptor - 22Mm X 25Mm

The Polyplumb MDPE Adaptor (22mm x 25mm) is a specialized transition fitting designed to seamlessly connect 25mm Blue MDPE water main pipe to 22mm copper or plastic pipework. Part of the original and trusted Polyplumb grey push-fit range, this adaptor is a critical component for bringing a mains water supply into a property and transitioning it to the internal plumbing system.

Material: Constructed from high-strength grey Polybutylene/Acetal, featuring a high-performance Stainless Steel Grab Ring for a secure, permanent mechanical joint.

Configuration: Push-Fit x Compression Transition:

MDPE End (25mm): A robust compression-style connection designed specifically for 25mm MDPE pipe.

The Installer's Advantage
The Polyplumb adaptor is the industry choice for a fast and reliable transition between external and internal systems. Its push-fit technology significantly reduces installation time compared to traditional brass compression fittings. The integrated stainless steel grab ring ensures the joint remains permanent and maintenance-free, providing peace of mind for installations where the pipework may be concealed in building voids or behind walls.
