If your unloader leaks while unit is running, replace this part. Adjust this part in or out to prevent leaking. 1/8" metric x 1/4" compression

These valves attach to the pressure switch and bleed off or "unload" excess air in the lines and off of your pump head so your air compressor can easily start up. This is especially necessary after the unit reaches its max pressure and shuts off; the schrader valve is tripped by a lever on the pressure switch, which opens the valve and bleeds the air from the unloader tube and discharge tube. If air leaks from this valve constantly after the units shuts off, replace your check valve, not the unloader valve.
