The John Guest push-fit polypropylene Speedfit-to-Speedfit shut-off valve is designed to isolate the water supply to a fixture or appliance. Quick and easy to install, it delivers a secure push-fit connection with a leak-tight seal—eliminating the need for tools, hot works, or sealing compounds.

Its distinctive collet locking design ensures the pipe is held firmly in place without distortion or restriction to flow. Corrosion-resistant and fully demountable, the valve supports enhanced system performance and helps reduce downtime during maintenance.

Constructed from polypropylene and fitted with an EPDM O-ring, the valve offers improved chemical resistance compared to the acetal version. 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.
