Flat face couplings made to the ISO 16028 Standard

15 November, 2018

The HQ Series flat face couplings are Holmbury’s flagship products, known globally for their leak-free performance in high pressure pulse, hammer circuits and many other applications. They are a preferred choice for many global OEMs.


The couplings are made of carbon steel with zinc nickel plating (1200 hours with no red rust in salt spray tests) and are fitted with Nitrile seals (Viton seals available). They are also available in AISI 316 stainless steel.

A safety locking sleeve is fitted as standard to prevent accidental disconnection. The flat faces are easily wiped clean and the flat face design prevents fluid loss during disconnection. Also, the coupling allows for minimal inclusion of air and contaminants during connection and has bidirectional flow. Accessories include dust caps and plugs, and parking stations are available.
