Features Quick release coupers are available in screw and flat face versions and are compatible with all the EUROPRESS product range and also interchangeable with most couplings used on high pressure hydraulic equipment. Flat face snap couplers are recommended because: – Anti-drip with negligible air or fluid inclusion during coupling and uncoupling operations ; – Easy to clean ; – Rotary motion which prevents hose twisting ; – Safe coupling system (two voluntary movemens are necessary for uncoupling).
