www.stauff.com/5/en/#169 169 HI Catalogue 5 § Edition 03/2024 STAUFF Screw-to-Connect Couplings Series HI § Carbon Steel Product Description Features Screw-to-connect couplings of the HI Series from STAUFF consist of a female body with a screw sleeve and a male tip with external thread. The Series is developed for high working pressure applications according to ISO 14540 and can be connected under residual pressure. 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 proven design is suitable for use in high pressure applications, such as cylinders and hydraulic tools and available in nominal sizes 6,3, 10 (1/4" - 3/8"). § Poppet Valve (HI) or Ball Valve (HIB) § Coupling made from carbon steel with Zinc/Nickel surface coating § Connect under residual pressure § ISO Interchange acc. to ISO 14540 Applications High Pressure Applications Top Features Vibration resistant Zinc/Nickel coating Connect Under residual pressure Designed for secure connection
