STAUFF Screw-to-connect coupling with poppet valve male tip QRC-HR-31-M-G20-B-W66I

Screw-to-connect couplings of the HR Series consist of a female body with internal thread and a male tip with a screw sleeve. The series is developed for particularly heavy-duty, high pressure and highpulsing applications for connecting hydraulic lines up to DN38 (1 1/2").

Coupling (screwing) and uncoupling (unscrewing) of the two halves is safe and very easy. After the connection is complete, all internal componentshave 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 occurwith push-to-connect couplings in similar extreme applications.

The proven design is suitable for use in heavy construction machinery and available in nominal sizes 10, 12,5, 19, 25, 38 (3/8" - 1 1/2").
