Flat Face Couplers for Mobile Equipment & Attachment Tools

Flat Face hydraulic couplers address residual pressure in a circuit, anywhere thermal expansion of trapped fluid causes pressure to develop. They connect by hand with residual pressure, without releasing any fluid into the environment, due to an internal valving system. The Flat Face design eliminates leakage and contamination in the circuit. The Series all interchange with ISO 16028 and their pressure ranges vary.
