Faucet Connector


Pro Water Parts is a distributor of quality John Guest fittings.

John Guest offers a wide range of push-fit connectors, tube and other fluid control products for drinks dispense and pure water applications.

Superseal is a special fitting designed to provide extra grip on hard steel, stainless steel and other polished metal tubing.

The Superseal design features a collet with integrally moulded stainless steel teeth similar to the standard Super Speedfit design, but incorporating an additional hand-operated nut and wedge shaped plastic washer to apply extra pressure to the collet and the double ‘O’ ring seals. This ensures that the collet teeth bite thoroughly into the tube to provide grip while at the same time, compressing the ‘O’ rings to further enhance sealing.

Like other John Guest fittings Superseal is suitable for potable liquids and other food quality applications.
