Nycoil uses a descriptive part numbering system for Pneumatic Couplers that takes the confusion out of matching couplers and plugs. Couplers and plugs have the same first three characters in their part numbers and are the same Interchange and body size, so they are compatible and can be connected. In addition, each character has a specific meaning that describes the particular coupler or plug.
