Rolair

O-ring for intercooler (top). Two required.

Air compressor discharge/bleeder valve with G-1/4" threads, FC2002, SCOUT, CIAO. Allows the pump to start more easily.  Note: This part has G-1/4" threads, not NPT.

Order rings if your unit is using oil and your valves are good. Hone the cylinder walls prior to installing. Order cylinder gasket if only removing cylinder and installing rings.
