The Series is developed for particularly heavy-duty applications for connecting hydraulic lines up to DN38 (1-1/2"). Coupling (screwing) and uncoupling (unscrewing) of the two halves is safe and very easy. The coupling is designed to open both valves when connected together and due to their rugged design, higher operating and burst pressures, they are well suited for heavy-duty service conditions in construction machinery. The Series was developed according to ISO 14541 in the following nominal sizes 06, 10, 12, 16, 19, 25, 38 (1/4" - 1-1/2"). The proven design is suitable for use in heavy construction. Other applications include attachments or equipment using high pressure, high impulse hydraulics, e.g. hydraulic hammers. § poppet valve § Zinc-Plating and Thick-Film-Passivation (Chrome III) § ISO Interchange acc. to ISO 14541 § Connectable up to 33% of working pressure with tools § Self-locking connecting thread § Feature: Black O-Ring External O-ring as a safety feature to indicate the complete/correct connection of the male tip and female body (the O-ring must be covered by the sleeve of the female body) Applications Construction Machinery Top Features Vibration resistant Designed for secure connection
