Safety coupling I.D. 7.8, Bi-Tec type, nickel-plated brass, R 3/8 ET, Operating pressure max. 20 bar, Temp. -20 °C to 100 °C
Safety air relief couplings for gaseous media.
Combination of a sliding valve and a quick disconnect coupling!
Connection is pressureless. Only a low spring force has to be overcome. Pressure only builds up when the blue sleeve is pushed forward. It is impossible to disconnect the hose either intentionally or inadvertently in this position. When the sliding sleeve is moved back into its home position, the air is relieved from the hose and the coupling can be disconnected.
