The H series is a further development of the standard hydraulic coupling, with some new materials to stand up to heavy conditions. The body of the coupling is made of steel so that the coupling functions reliably even when subject to substantial lateral forces and high impulses.

Connected length in total:
H5000 = 82 mm
H7500 = 91 mm
H10000 = 108 mm

High flow rate – minimum pressure drop. Twice as safe through a double sealing. Safety closing ring prevents unintentional uncoupling. Maximum protection against corrosion. Small dimensions. Pressure eliminator for coupling and plug available. Possible to connect up to working pressure.
