The new flat-face series FFH has notably higher
performances than FFI couplings. They also
exceed the performances requested by ISO
16028 regulations.
Working pressure has been raised to 35MPa and
the flow rates have been highly improved.
FFH couplings have undergone severe impulse
tests in order to check their resistance to pressure
peaks within the systems.
A further plus is the Zinc-Nickel surface treatment
which improves their resistance to corrosion
