Catalogue 5 - STAUFF Quick Release Couplings 173 HT Catalogue 5 § Edition 03/2024 STAUFF Screw-to-Connect Couplings Series HT § Carbon Steel Product Description Features Screw-to-connect couplings of the HT Series from STAUFF consist of a fe- male body with a winged screw sleeve and a male tip with external thread. 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. Series HT are used on Hydraulic tippers, commercial vehicle trailers, agricultural and construction equipment and available in nominal sizes 19, 25 (3/4" - 1"). § Poppet Valve § Coupling made from carbon steel with Zinc/Nickel surface coating § Heavy duty internal components § Connect under residual pressure Applications Top Features Vibration resistant Zinc/Nickel coating Connect Under residual pressure Hydraulic tippers Designed for secure connection
