Quick couplings
FF Cupla
The Nitto Kohki FF Cupla is a flat-face quick coupling in steel with an NBR seal, available in nominal sizes 3, 4, 6 and 8 as plug (P) and socket (S). The flat-face design closes both coupling halves flush, eliminating spray when disconnecting under pressure and reducing leakage to a minimum. FF Cupla is suitable for compressed air and other gaseous media at low to medium operating pressures.
