Hubbell Pressure Switch, 1-Port, 140/175 PSI, With Unloader Valve #048AA0

Hubbell HC69JG109835R Air Compressor Pressure Switch. This switch has a factory setting of 140 PSI on and 175 PSI off, but is adjustable. Rated at 20A/120V. This UL and CSA approved.

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.

• Cut-in PSI = 140 PSI
• Cut-out PSI = 175 PSI
• 1/4" female NPT manifold port
• Manual on/off lever switch
