STAUFF Screw-to-connect coupling Flat-Face male tip QRC-FG-25-M-30SB-S5-W3

Flat Face screw-to-connect couplings of the FG Series consist of a female body with a screw sleeve and a male tip with external thread. The Series is developed for particularly heavy-duty applications for connecting hydraulic lines up to DN31,5 (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 FG Series is available in nominal sizes 10, 12, 16, 19, 25, 31,5(3/8" - 1 1/4").
