John Guest push-fit polypropylene Speedfit push-fit to male shut off valve (NPTF Thread) isolates supply to a fixture or appliance. Fast and simple to install, John Guest valves create an instant push-fit connection and leak tight seal without the need for tools, hot works or sealing agents.

The unique collet locking design firmly and securely holds the pipe in place without deforming the pipe or restricting flow. John Guest push-fit valves are corrosion resistant and fully demountable, improving system performance and reducing system downtime during maintenance.

Manufactured in polypropylene with an EDPM O-Ring, the valve offers greater chemical resistance than the push-fit acetal valve and is suitable for potable water (10 bar at 20°C), intermittent hot water (4 bar at 60°C), water treatment and purification applications. All John Guest fittings are manufactured and assembled in the UK.
