The Stopcock MDPE Poly Brass VSP (25mm x 22mm) is an essential utility control valve designed to provide a secure transition and shut-off point between an external 25mm MDPE (Medium Density Polyethylene) underground water supply pipe and internal 22mm copper plumbing. Ideal for domestic boundary boxes, main water entry points, and utility rooms, this valve allows installers to reliably isolate the main water supply to a building when required for maintenance, repairs, or emergencies.
 
Manufactured from high-grade, corrosion-resistant brass with robust compression and push-fit/grip ring mechanisms, the fitting complies with relevant water supply industry regulations (such as WRAS-approved specifications). It features a secure compression connection on the 25mm MDPE side—complete with a supportive plastic liner—and a standard compression joint on the 22mm copper side, ensuring a watertight, high-pressure seal without the need for specialized welding.
 
Engineered for durability and ease of operation by professional plumbers and certified utility installers, the stopcock incorporates a smooth-turning manual handle or T-key socket depending on the specific valve configuration. Whether you are connecting a new-build property to the main water supply, replacing a failing external boundary valve, or upgrading a domestic water intake system, this trade-quality brass stopcock delivers dependable flow control, excellent longevity, and complete regulatory compliance.
