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

Screw-to-connect couplings of the PS Series consist of a female body with external thread and a male tip with a screw sleeve. The Series is developed for particularly heavy-duty hammer applications and for connection of different booms in High Reach Demolition machines forconnecting hydraulic lines in DN25 (1 1/4").

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 PS Series is available in nominal size 25 (1 1/4").
