The John Guest push-fit polypropylene Speedfit-to-Speedfit shut-off valve is designed to isolate the water supply to a fixture or appliance with ease. Simple and quick to install, it provides a reliable push-fit connection and a leak-tight seal—no tools, hot works, or sealing compounds required.

Its innovative collet locking design securely holds the pipe in position without causing deformation or impeding flow. Corrosion-resistant and fully demountable, the valve supports improved system performance and helps minimise downtime during maintenance.

Manufactured from polypropylene and fitted with an EPDM O-ring, the valve offers superior 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.
