Description
Air compressor check valve, 3/4" Compression x 3/4" MPT with 1/8" FPT side port.
If the small unloader (bleeder) valve on or under your switch leaks constantly AFTER the unit shuts off, replace this part. The check valve is a one-way valve that prevents air from backfeeding from the air tank.
