John Guest Speedfit 12mm Female to 1/2" BSP Female

John Guest Female Adaptor 1/2″ BSP to 12mm Push-Fit fitting for connecting 12mm semi-rigid pipework to a 1/2″ BSP type fitting. John Guest push-fit fittings create an instant push-fit connection and leak tight seal without the need for tools, hot works or sealing agents. This fitting is compatible with 12mm John Guest semi-rigid pipework and also the Whale 12mm semi-rigid pipework. The push-fit connector has a unique collet locking design which firmly and securely holds the pipe in place without deforming the line or restricting flow. Fittings are corrosion-resistant and fully demountable, improving system performance and reducing system downtime during maintenance. Can be used on hot or cold pipework. These are the correct inlet/outlet fittings for Shurflo/Fiamma/Seaflo pumps & accumulators.
