Air Pressure Switch 85-100 PSI 1/8"-27 NPT DC 24V 12V Air Compressor 100PSI DC

Worked great. Shut off 100. Turn on at 80

I have a harbor freight pancake compressor which had worked great for many years. Then suddenly it would intermittently not turn off popping my high-pressure relief. I needed one of these to fix it and now it works great again.

So I have a stupid Porter Cable Pancake Compressor that has a a pressure switch that shut off at 150 lbs, same compressor is oil less, never buy an oil less compressor talk about junk. The piston ring is made of cardboard. So getting to this pressure switch. My compressor even after a new ring and cylinder quickly couldn’t reach the 150 lb preset on the factory pressure switch. A new ring only reached pressure of 150 3 or 4 times before it wouldn’t reach pressure and then would not shut off. Never would there be a reason for a 4 gallon compressor to need to reach 150 lbs., and it took forever to go from 120 to 150. A parts store wanted $40 for a switch that would shut off at 120 lbs. compressor not worth putting that much money into. Looked on Amazon found these. Now compressor working fine shutting off at 100 lbs. Which is all I need from it. This switch saved tool from junk yard.Only reason it’s not a 5 star is haven’t had it installed long enough to evaluate durability. By itself install a simple plug in, but was a bitch to access the location in my terrible PC compressor

awesome

Just what I needed

As represented

Works well

Unless my gage is way off by 20psi I stop it at 125 worried my tank is going to explode
