Review on Upgraded Central Pneumatic Air Compressor Pressure Switch Control Valve: Replacement Parts for 90-120 PSI, 240V Air Compressor by Ronnie Segobiano

Yes, it's the exact replacement for my free 4 gallon compressor. It works as it's supposed to and it was a much better price than the alternatives. Why a score of four and not five? The first one broke. The cover, which also houses the switch, was broken somewhere in the distribution chain. The device is packaged in bubble wrap in a Revain envelope. A box would have been much better and possibly cheaper. I have to say that Revain was quick to respond to return it at their expense and send me a new one. Yes, it lacks the ground screws on the side like the original. I could drill holes and use copper clips from the old one. Or, as one person suggested, just attach flat clips to one of the small screws holding the switch to the valve. One reviewer suggested the metal part was cheap since he broke it while spinning. I was careful with this but turned around a lot to make sure it was tight. It was such a difficult turn that I felt I needed it. All of this works for me.
