FF Series Couplings are non-spill, push-to-connect quick disconnects designed for use in the construction and utility markets.   The push-to-connect sleeve allows one handed connection and features a locking mechanism to prevent accidental disconnection.  The flush face design eliminates hydraulic spillage and air inclusion when connecting and disconnecting.  Anti-blowout seal on the male half prevents damage and premature failure with residual system pressure.  Coupling bodies are steel with zinc and clear trivalent chromate plating (hexachromium free).

Available in body sizes 1/4" through 1" with female pipe thread (NPSF), male pipe thread (NPTF), female straight thread (ORB), and female British Standard Pipe Parallel (BSPP) as standard end configurations.

The FF Series 3/8" size conforms to HTMA (Hydraulic Tool Manufacturers Association) standards and both coupler and nipple are marked with a directional flow arrow.
