1/4 Inch Industrial Steel Coupler x 1/4 Inch Female NPT, PK 50

The INTERSTATE PNEUMATICS CH440-50K is an industrial coupler identified as the female component of a quick-connect fitting system. It provides a mechanically secured connection using a Buna-N sealing element within the specified temperature range, supporting quick coupling and decoupling with compatible male/female quick-connect components (tool-free operation as described by product design). Made with a steel body and a zinc-plated coating, it is compatible with industrial interchange systems and supports a nominal body size of 1/4 inch. The coupler connects via a 1/4" FNPT threaded female port and includes a stainless steel spring to support locking engagement using the included stainless steel spring. Its sealing element is made of Buna-N (Nitrile), rated for operation within -40°F to 212°F.
