Couplers - Import export

1.5 ~ 2 Times Higher Flow. High flow type with "airless valve shutoff" design. Compared with Nitto’s conventional 35MPa Cuplas, the flow volume is increased 1.5 to 2 times. *Increase ratio of each flow volume depends on the Cupla size. "Airless valve shutoff" design minimizes spillage volume on disconnection and admixture volume of air on connection. Best suited for hydraulic lines with drastic high pressure pulsation such as in diecasting machines. Pushtoconnect operation and sleeve stopper design preventing accidental disconnection under vibration or impacts enhances workability and safety. Sizes are Rc 3/8, Rc 1/2, Rc 3/4, and Rc 1. *Only the same size of socket and plug can be connected.

Pressure ratings comparable to steel Cuplas. A builtin "automatic lock mechanism" to lock the sleeve when connected, thus prevents accidental disconnection. Just push plug into socket for simple connection. Can be used for air and water. Less likely to damage painted or easily dented surfaces than metal couplings. Air flows in either direction from plug or from socket side when coupled. Plug and socket with hose guard nut are also available (see the pages of NK Cupla Hose / NK Cupla Cpil Hose for details).
