STAUFF Screw-to-connect coupling with poppet valve male tip QRC-HV-51-M-G32-B-W66I

Screw-to-connect couplings of the HV Series consist of a female body with a winged screw sleeve and a male tip with external thread.

Coupling (screwing) and uncoupling (unscrewing) of the two halves is safe and very easy. After the connection is complete, all internal components have minimal play or clearance, which significantly reduces the risk of material fatigue.

Another advantage is that the risk of permanent indentation, so-called "brinelling", on the surface of the male tip is eliminated, which can occur with push-to-connect couplings in similar extreme applications.

The Series HV is available in the nominal sizes 19, 25, 31, 38, 51 (3/4" - 2").
