Safety coupling NW 7.4 spout for 6 mm LW nickel-plated brass. Single–hand safety couplings with double locking. / Coupling is performed by simply pushing the plug into the coupling as with standard couplings. When decoupling, the first lock is released by pushing back the locking sleeve. / The coupling valve closes. Now the compressed air can escape from the plug (hose). / The second locking system is released by actuating the unlocking bushing again. / Only now the connection can be released. / The system fulfills the requirements of ISO 4414 and is BIA-compliant.
