STAUFF Screw-to-connect coupling with poppet valve series HR

Screw-to-connect couplings of the HR Series consist of afemale body with external thread and a male tip with a screw sleeve. TheSeries is developed for particularly heavy-duty, high pressure and high
pulsing 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").
