Check Valve #05943C

Old Part Numbers: E100099

Air compressor check valve. The manufacturer used two check valves on this unit in the past, but this is now the only check valve available (the other is obsolete). If looking directly at the hex fitting, the small male thread for the bleeder line is on the RIGHT side.

If your pressure switch leaks continuously from the unloader valve after the unit shuts off, replace this part.
