Pneumatic Quick Fit Couplings

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 adaptor (the male part).
