FH/FF/FX/FU

Particularly user-friendly

The FF series represents the consequential advancement of the long standing and proven flat seal couplings of the FH series. The use of better quality materials allows for even higher operating pressures than those pressures stated in the standard ISO 16028.

The function of the flat seal couplings is widely known. Innovative to the series FF is that all sizes are by default equipped with a safety system against accidental decoupling which the user can activate as an option.

The construction of the flat valves ensures that coupling and decoupling only leads to minimum oil losses and/or air locks.

The major areas of use of these couplings are engines in environment critical areas and hydraulic tools. Their modular architecture ensures the availability of a large quantity of connections complying with international standards.
