CAC-4290-2 Check Valve, 3/8 in. Inlet, 450 PSI

The CAC-4290-2 valve was an air compressor check valve for several air compressor brands. Valve CAC-4290-2 has a 3/8 in. inlet port and a 1/2 in. compression outlet.

A check valve is designed to help prevent backflow in an air compressor. When air flows backwards through a compressor, it causes the check valve to shut and prevent airflow.

This CAC-4290-2 check valve was used in select air compressors from several major brands, such as DeWalt, DeVilbiss, Porter Cable, Craftsman, and many more.
