Air Compressor Pump O-Ring Gasket Kit #0597AC

Air compressor o-ring kit includes the upper and lower valve plate o-ring seals.

If the compressor pump doesn't seem to pressurize as quickly as it should or is leaking in between the head, valve plate, cylinder, or crankcase while running, there's a good chance you need to install new gaskets. You can spray soapy water on the pump while it's running to inspect if there are any bubbles forming, which would indicate a leak.
