The Series is developed for high working pressure applications for connecting hydraulic lines up to DN51 (2"). 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 and available in nominal sizes 10, 12,5, 19, 25, 31, 38, 51 (3/8" - 2"). § Poppet Valve § Coupling made from carbon steel with Zinc/Nickel surface coating § Connect under pressure § Heavy duty internal components § Wide of range for normal sizes up to DN51 (2'') Applications High Pressure Applications Top Features Vibration resistant Zinc/Nickel coating Connect Under pressure Designed for secure connection
