The John Guest push-fit polypropylene Speedfit-to-Speedfit shut-off valve is designed to isolate the supply to a fixture or appliance with ease. Quick and straightforward to install, it forms an instant push-fit connection with a leak-tight seal—no tools, hot works, or sealing agents required.

Its unique collet locking mechanism securely holds the pipe in place without causing deformation or restricting flow. Corrosion-resistant and fully demountable, the valve enhances system performance and helps minimise downtime during maintenance.

Manufactured from polypropylene and fitted with an EPDM O-ring, this 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.
