Quick Connect Couplings

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).
