STAUFF Screw-to-connect coupling Flat-Face male tip QRC-HM-31-M-NF20-B-W162I
- ERIKS:14508453
Screw-to-connect couplings of the HM 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.
The Series HM is available in the nominal sizes 19, 25, 31, 38 (3/4" - 1 1/2").
