Condor MDR21 Pressure Switch, 100/135 PSI, 4-Port, 90 Unloader, On/Off Lever #05C18B

Air compressor pressure switch, 100 PSI cut-in / 130 PSI cut-out, 4 port, MDR21-style with 90-degree quick-connect unloader valve and auto on/off lever.

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.

Note: This switch can be set for a maximum of 160 PSI, but is preset to 100/130 PSI.
