John Guest push-fit acetal service valve metric 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 ¼ turn screwdriver slot and is also suitable for hot and cold water applications.

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. All John Guest fittings are manufactured and assembled in the UK.
