Description

The SS3L3, SS4L5 & SS5L5/N5 are single-stage compressors, and they cycle across a lower pressure range than the two stage machines in the Ingersoll Rand line. This is the pressure switch built for them: 100 psig cut-in, 135 psig cutout, factory set. That range is the reason to order by part number rather than by appearance. The 135/175 psig switches used on other 2340 and 2475 units look similar and thread the same way, but fitted to an SS3L3, SS4L5 or SS5L5/N5 they ask a single-stage pump to run past the pressure it was designed for. Matching the switch to the compressor is what keeps the duty cycle, the motor load and the pump life where Ingersoll Rand intended them. The switch includes a manual shut-off lever on the side of the body and a NEMA type 1 enclosure suited to normal indoor shop conditions. OEM part number 23474661. Check the model on your compressor's data plate before ordering, use Teflon tape on the threads at installation, and contact Ingersoll Rand Air Tech support if you need the fit confirmed or help with installation they can be reached at

    • Fixes the failure to stop the motor once pressure is reached.
Product worked great.

    • Hope the new one lasts as long as the original
Just put one of these on my SS4L5 model purchased in 2014. The original finally quit on me, the contacts got stuck. I don't use it much probably why it made it 12 years. If this one lasts that long, I'll be all good with it. It fit and works like a champ. Only have one cycle on it butt was super easy to install and a direct fit. The part numbers are the same the listing just doesn't have the SS4 listed as compatible. ... show more

    • Pressure Switch
Hopefully this pressure switch lasts a little longer. This switch was purchased to replace the switch on our air compressor in the shop. Relatively easy to install and adjust.

    • Upgraded replacement for the original failed switch
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. ... show more

    • Fixed my issue
Purchased this as a replacement part for my Ingersoll SS4 We have a small auto repair shop and use this compressor daily. After a year of daily use the compressor would fail to stop once reaching 135psi. Under normal working conditions the compressor is turned on and once it reaches 135PSI it turns off. Once the compressor goes below 100 psi it kicks back on and stops when it reaches 135psi again. Well the compressor would fail to turn off after reaching 135psi and would make a loud clacking noise. We would have to unplug the compressor as even the off switch wouldn't turn it off. I replaced this switch and now it works as intended. It fixed my problem but I'm bummed that we had this issue in the first place. ... show more

    • OEM
OEM quality make sure it is the correct pressure range for your unit?

    • Incorrect pressure
Works as it should however my pressure switch came at a 135 to 175 cut off not the hundred to 135 PSI psi. With the pressure adjuster screw all the way out it activates at 105 and shuts off at 140 psi

    • JUNK AND VERY DISAPPOINTED
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. ... show more
