V&G Compression Stopcock (Poly x Poly)

The V&G Compression Stopcock (Poly x Poly) from Evolve is a reliable and easy-to-install valve designed specifically for use with polyethene (poly) pipe systems in both domestic and commercial settings. Whether you're installing a new water supply or replacing an old valve, this stopcock gives you convenient control over your system—letting you shut off the water whenever needed for maintenance or emergencies. Constructed from durable brass and approved to WRAS standards (Approval Number: 1403907), this stopcock is built to last. Its compression fittings make installation quick and simple—there's no need for soldering, heat, or specialist tools. Just position the valve between two lengths of poly pipe and tighten the compression nuts to create a secure, watertight seal. This version is specifically designed for use with MDPE or other compatible poly pipe systems and is available in both 20mm and 25mm sizes. It’s an ideal solution for outdoor water supply lines, underground installations, or anywhere plastic pipework is being used.
