Flat Face Couplings

Flat face couplings, including Holmbury’s flagship HQ series, are renowned for high performance and easy wipe clean faces. Minimal fluid loss on disconnection. Minimal air or contaminant inclusion during connection. Safety locking sleeves included on most variants. The choice of many global OEMs. The ISO16028 was written around the original Holmbury coupling design.
