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 provides a secure push-fit connection with a leak-tight seal—no need for tools, hot works, or sealing agents.

Its advanced collet locking mechanism holds the pipe firmly in place without causing deformation or restricting 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 enhanced chemical resistance compared to the acetal variant. 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.
