FF Cupla

The Nitto Kohki FF Cupla series is a flat-face quick-disconnect coupling designed to eliminate fluid spillage at connection and disconnection - a critical requirement in pneumatic circuits where oil mist contamination must be controlled. Operating at pressures up to 10 MPa (1,450 psi) with residual pressure below 0.05 MPa for safe dry disconnection, FF Cupla couplings achieve a leak rate of <1 cm³/min in the closed position, meeting the flat-face seal requirements referenced in ISO 16028. The double-sleeve locking mechanism provides a positive connect confirmation and prevents accidental release under vibration loads common in industrial automation environments.

esd.equipment supplies the complete Nitto Kohki FF Cupla range - 8 SKUs available including plugs, sockets, and matched sets across NPT and BSP thread configurations. As an authorised distributor for Nitto Kohki pneumatic components, all products are shipped from verified stock with full manufacturer traceability, compliant with ISO 4414 pneumatic system safety guidelines.
