Check Valve 3/8" FPT x 1/2" MPT with Cold Start Valve #1162E3

Old Part Numbers: CTB3812-P1-SU3

Check Valve 3/8" FPT x 1/2" MPT with cold start valve for air compressors. The check valve is a one-way valve that prevents air from back-feeding from the air tank. If the small unloader (bleeder) valve on or under your switch leaks constantly AFTER the unit shuts off, replace this part.

Note: This check valve is for serial numbers without the prefix (A). For Emglo units, order this part if you have the AM79 model.
