Description

Air compressor check valve. 3/8" Comp x 1/2" MPT with 1/8" FPT side port. 

The check valve is a one-way valve that prevents air from back-feeding from the air tank. If your unit has a hard time restarting when trying to cycle or your pressure switch is leaking out of the small bleeder valve on the side (or underneath), order this valve.

Note: The replacement valve may look different from the original part.

    Not like the original where the discharge pipe slips through the valve. There is a shoulder inside that will require you to reset your nut and ferrule if you are using your original pipe.
