This range of G-Link quick disconnect couplings from Goodridge feature FPM seals which are suitable for use with fuel, bio diesel, ethanol and vegetable oil. The locking mechanism is designed for one handed operation, no separate actuation of the retaining sleeve is required for operation.To verify the correct connection, the female half is equipped with a green indicator ring. This indicator ring can, alternatively, be replaced by a retaining clamp. This can only be attached when the halves are coupled and eliminates the risk of unintentional uncoupling. Both halves of the couplings are equipped with self-acting valves to stop loss of fluid during uncoupling, as well as air inclusion during coupling. Additionally the whole operating mechanism is O-Ring-sealed to achieve particular suitability for rough conditions and to reduce environmental effects.G-Link Quick Disconnect Couplings are manufactured only from high-strength certified materials. All parts are produced to meet the highest
