The Series is developed for extra heavy-duty applications for connecting of large diameter hydraulic lines up to DN 25 (1''). 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 heavy duty construction and transportation modules, drilling rigs and trailer equipment. Other applications may, depending on the pressure and flow characteristics, include oil equipment steel mill machinery, and other demanding hydraulic applications. The RH Series is available in nominal sizes: 10, 12,5, 16, 19, 25 (3/8" - 1"). § Flat Face § Coupling made from carbon steel with Zinc/Nickel surface coating § Sealing’s made from FKM (Viton®), HNBR, PTFE § Heavy duty internal components § Suitable for panel mounting Applications Self-Propelled Modular Transporters Top Features Zinc/Nickel coating Vibration resistant Suitable for panel mounting Designed for secure connection
