Hubbell Heavy Duty Pressure Switch, 1-Port, 100/125 PSI, With Unloader Valve #048A9B

Hubbell 69HAU2 Heavy Duty Pressure Switch, 1-Port (1/4" female NPT), 100/125 PSI factory preset with unloader valve.

Replace the pressure switch if the compressor no longer cuts in or cuts 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.
