078 Series | Safety Lock Breathing Air Quick Release Couplings & Plugs
The 078 Series is a 7.4mm safety lock quick release coupling designed for self contained breathing apparatus (SCBA) applications. To disconnect, the plug must first be pushed further into the coupling before it can be released — this deliberate two-step action prevents unintentional disconnection in safety-critical environments.
High flow performance with low pressure drop. BSPT male thread, BSPP female thread and hose tail options available. Coupling and plug caps supplied separately.
