Pneumatic Parts (Female Coupling)

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).A female coupling is a receptacle that holds the male jack in place thus performing sealing functions.
