Switch was a perfect replacement and worked perfectly. Assembly was not an issue.

This pressure switch was an exact replacement for the a Central Pneumatic (Harbor Freight) 2 HP 4 Gallon air compressor model 95498. This appears to be the exact switch it was built with.I did find that the cable clamps were different than the original. Initially I tried leaving the clamps on the electrical cables and screw the bottom part into this switch. The screw part did not mate with the new switch though. This wasn't a big deal, it just meant sliding the old clamp and screw fitting off both cables and using the new ones that were supplied with the switch. This is the only thing I found different between the OEM switch assembly and this one. Just use the new fittings supplied and but on both sides of the cables (inside and outside the case) before wiring up the cables.These switches apparently use a rubber diaphragm as part of the design. Over time the rubber degrades and fails, then air pours through the diaphragm. This results in the air compressor having no pressure. It is a bit hard to hear where the leak is because of the noise of the compressor, and the air leaks so fast that you only have a second or two after turning off the compressor to find it. If you have a compressor with this type of switch, it is likely the case. Take the cover off an you will feel the air leaking out.My compressor was working when last put away. When I went to use it again after being stored for some time it had no pressure. The diaphragm of these switches will fail just sitting.Note that changing this switch, at least on this compressor was a pretty big job. They appear to literally put the switch in and build everything else around it! The tip is to first disconnect the air line to the compressor, disconnect the compressor electrical wires, then slide the entire compressor assembly on its mount off the base. This will give more room to work, and to disconnect the gauge, regulator and outlet. This switch also serves as a type of manifold, and it isn't an exaggeration that everything needs to be disassembled, then reassembled essentially in reverse order.I did use OATELY Pipe joint compound on the fittings when reassembling.The switch worked properly, and was properly calibrated at 100 PSI.I expect this switch is exactly the same as the original, so hopefully lasts another 10+ years or so before it fails again.

The switch leaks air at the diaphragm. The threads in one of the four screw holes in the (manifold diaphragm and switch assembly) was stripped out not allowing it to seal and causing an air leak. Bad design. There should be a nut and bolt configuration like my old switch had. Relying on machine screws to thread into a die cast manifold is a major failure point. I ended up drilling out the screw holes all the way through and reassembled it using the old nuts and bolts from my old switch. This is holding nicely with no leaks. Not sure what other defects I may discover down the road.

Used this to replace power module with leaky/bad diaphragm on 10 gal. Brute compressor.Replacement was easy, everything went together smoothly.Did not come with screws/keepers for ground wires, so be sure to keep the ones from the part being replaced.

Worked to repair a 10 gallon 120psi compressor that wasn't that old but decided to leak from it's inside seal,,easily replaced but in my case I had to reverse the steps to remove the old one and it took 2 tries,,works fine again now

I bought it for the rubber baffle. Used it in my old one that was blown. Fit perfect. Its a shame you cant just buy the baffle seperate. Air compressor works again.

Yes, this is an exact replacement for my 4 gallon, freebie compressor. It works like it is supposed to work, and it was a far better price than alternatives.Why a four rating instead of a five?The first one arrived broken. The cover that also contains the switch had been broken off somewhere in the distribution chain. The unit is wrapped in foil covered bubble pack in an Amazon envelope. A box would be far better, and possibly cheaper. I must say that Amazon responded quickly to return it at their cost, and to send me a new one.Yes, it is missing the grounding screws on the side as the original had. I could have drilled holes and used the copper clips from the old one. Or, like one person suggested, you simply attach the spade clips to one of the small bolts holding the switch to the valve.One reviewer suggested that the metal portion was cheap as he broke it while twisting it on. I was careful with that but I turned hard to assure the seal. It took as hard a turn as I felt I needed.It all works for me.
