Ingersoll-Rand 23474661 Pressure Switch for Single Stage Compressor SS3 And SS5

Perfect fit for SS 4 ingersol Rand upright compressor

This was exactly what we ordered. It’s installed and working as expected

We needed this for our air compressor it works just like the original

The pressure switch failed after several years on my SS5L5 compressor. I was working in the shop and paused to wonder... what is that awful noise. The poor pump head was trying its hardest to shove 145-150psi into the tank, which is apparently the mechanical limit of the pump, and the noise it created was loud, funny if not borderline terrifying. This switch was a drop in replacement and already calibrated correctly. I did have to refabricate the unloader tube in my case as the old and new attach to the switch a little differently but that was simply done with automotive brake line bending pliers.

Works good

This definitely did not fit the TS5 compressor. I needed to cannibalize the old one for a number of parts. First it has no accommodation for a pressure relief valve which I consider a serious omission since these things always fail with the points closed. It had a port of 1/2 inch instead of the 3/8th inch the original had and the piping was configured in a rather different direction. I had to remove the aluminum port structure from the old one and put it on the new one. It also has a different shut off pressure, of 135 as opposed to 150. But it works OK and I didn't have to have the 150PSI in the shop. Trying to find the OEM replacement was not happening, at least not from Amazon. I'm just writing this as a caution for others. The tool is up and running again with some effort and a mess of tools..

This thing is junk!! As another person posted its does not kick on or off at the correct PSI. I bought this in May and its now July and it will not kick on automatically. I have to switch it off and back on maunally for it to come back on again. It worked fine for just over 2 months and is now junk. The pressure switch this replaced was also a IR brand and that one lasted about 3 years. That one replaced my original factory one that lasted much longer and that one should have lasted nearly a lifetime.Either way, I'm not buying these OEM ones anymore. They cost WAY too much to have puke out as soon as they do.

I’m not sure if people are just outright guessing and ordering the wrong part number but I bought one of the return switches. It was unused as I suspected and was the correct part number 23474661 The install was simple using a Phillips screwdriver, 7/8” wrench and 1/2” wrench.
