Quickly and safely isolates a branch feed from the mains supply via an integrated ball valve

John Guest push-fit acetal angle stop valve isolates an appliance or fixture branch feed without affecting the main supply line. The valve includes an integral service check valve for backflow prevention up to Fluid Category 2 and a ¼ turn chrome plated ball valve. 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 acetal with a food grade nitrile O-Ring, valves are suitable for foodstuff, potable liquids (10 bar at 20°C), inert gases and intermittent hot water applications (4 bar at 60°C). All John Guest fittings are manufactured and assembled in the UK.
