The Plasson Dedicated Copper Fitting / Reducing Set (25mm - 22mm) is a specialized utility transition component designed to bridge an external 25mm metric MDPE (Medium Density Polyethylene) water supply pipe directly onto a standard 22mm copper pipe. It is widely utilized by plumbing and utility professionals during building renovations, boundary entry point retrofits, and service repairs where modern plastic underground mains must link cleanly to internal copper networks.
 
Manufactured from high-grade virgin polypropylene and robust engineering components, this fitting provides exceptional impact strength, environmental stress resistance, and complete immunity to corrosion. The assembly incorporates precision-engineered internal gripping elements and seals that lock securely onto both the polyethylene and copper tubing, maintaining structural stability without the risk of pipe distortion or pull-out under pressure.
 
Engineered for straightforward and efficient on-site installation, the component converts standard Plasson compression fittings to accept copper pipe sizes accurately without requiring complex conversion hardware. Fully WRAS-approved for wholesome potable water applications and rated for high working pressures up to 16 bar (PN16), this trade-quality copper adaptor delivers long-term reliability and a dependable, leak-free transition for cold water supply systems.
