3/8 Inch Industrial Steel Coupler x 1/4 Inch Female NPT, PK 25

The INTERSTATE PNEUMATICS CH640-25K is an industrial coupler designed as the female half of a quick-connect hose fitting. It provides a threaded coupler interface intended to connect to compatible male quick-connect fittings. It enables connection and disconnection without requiring tools when used with compatible quick-connect plugs. Constructed primarily of steel with a zinc-plated finish, it supports rapid, tool-free connection and disconnection for use in specified pressure application requirements (if pressure rating is available); otherwise, it is intended for industrial transfer system applications. The coupler features a 3/8" body size and a 1/4" FNPT threaded connection, aligning with the industrial interchange standard for compatibility with corresponding fittings.
