John Guest push-fit valve is used to temporarily shut off hot or cold water supply to a drinks dispense fixture or fitting. The ball valve is easily operated with a quarter turn screwdriver slot and is also designed for hot and cold water applications. Valves create an instant push-fit connection and leak tight seal without the requirement for tools, hot works or sealing agents. Its unique collet locking design firmly and securely holds the pipe in place without deforming the pipe or restricting flow.
