This John Guest push-fit polypropylene Speedfit-to-Speedfit shut-off valve is designed to conveniently isolate the water supply to a fixture or appliance. Its quick and easy installation creates a secure push-fit connection with a leak-tight seal—no need for tools, hot works, or sealing compounds.

The valve features a unique collet locking system that firmly holds the pipe in place without distortion or flow restriction. Corrosion-resistant and fully demountable, it supports improved system performance and helps reduce downtime during servicing.

Constructed from polypropylene and equipped with an EPDM O-ring, the valve offers enhanced chemical resistance compared to the acetal alternative. It is suitable for potable water (10 bar at 20 °C), intermittent hot water (4 bar at 60 °C), and applications involving water treatment and purification. All John Guest fittings are proudly manufactured and assembled in the United Kingdom.
