Pressure Switch, 145/175 PSI, 4-Port #080B32

Four (4) 1/4" FPT ports on bottom of switch. Preset to come on at 145 and cut off at 175 psi. Side mult-position unloader valve for 1/4" rigid line. Can be used with nylon lines as well by adding a plastic ferrul and insert. (63P-4) (60PT-4).

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.
