STAUFF Screw-to-connect coupling with poppet valve male tip QRC-HH-51-M-N32-V-W5K

Screw-to-connect couplings of the HH Series made of stainless steel consist of a female body with a screw sleeve and a male tip with external thread.

The Series is developed for high working pressure applications for connecting hydraulic lines up to DN51 (2").

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 ofmaterial 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 proven design is suitable for use in high pressure applications and available in nominal sizes 10, 12,5, 19, 25, 31, 38, 51 (3/8" - 2").
