Description
The Condor 31QA3EGX OEM pressure switch replacement is an MDR3 style, 1-port, 1/4" female NPT pressure switch with straight compression style unloader valve and is preset to 120/150 PSI. Does not have on/off dial switch.
Replace the pressure switch if the compressor no longer cuts in or out at the designated pressure (PSI), if the unit doesn't turn on or off, or if there is an obvious air leak from the contacts or manifold.
If the small unloader (bleeder) valve on or under your switch leaks constantly AFTER the unit shuts off, don't replace this part, replace the in-tank check valve. Most pressure switches have a bleeder valve which has a 1/4" plastic or copper line routing to it.
