A pneumatic coupling is used to connect compressed air tools to a compressed air line. A pneumatic coupler allows a tool to be easily connected or disconnected to a hose or pipe while it is under pressure.
The system consists of two parts: the quick coupling (the female part) and the plug-in or nipple (the male part).
Japan Nitto Type quick couplers provide quick and easy connection/disconnection of air lines. They completely eliminate the inconvenience of connecting/disconnecting conventional thread type couplings or flanges, and hose kinking, while providing quick, convenient control and maintenance of air line connections.
