Safety Lock Couplings & Nipples

Safety lock couplings are specially designed to prevent unintentional disconnection during operation. An added locking function requires the operator to “unlock” the coupling before it can be disengaged. The safety lock couplings are one-hand operated during connection but require two hands for disconnection.
