LEFOOAir Compressor Switch Pressure Control Switch Valve for Air Compressor Replaces Furnas Square D H4 - Lf10-4h-1-npt1/4-140-175

Easy to install replacement. Works perfectly and easy to adjust

This switch worked great on my little craftsman compressor.. Took a litlle bit of adjusting to get the pressures right, but works like new now. If you can do the installation, you will have no problem with the set up. It just takes a little time. Buy this switch!

These are typical chinese garbage. They are not Square D, use new safety relief valve! They do NOT adjust correctly and will both Over and Under Pressure randomly. Spend the extra money and buy Square D Amazon sells them also.

this switch was bought to replace the lefoo switch on a harbor freight air compressor, it is a much more solid unit and NOT an exact duplicate (the bottom of the switch is metal rather than plastic, and the one I received was the "140/175" cut on/off switch, not the 90/120 adjusted higher, thought I did have to adust down the 140/175 switch to work with the hardbor freight belt driven 29 gallon compressor (120/150 factory settings)

was easy to install but ends there. works fine for 20 - 30 minutes of use and then no air and compressor is off at 30 psi have to go to new control and wiggle on/off switch and compressor starts and will be fine for another 30 minutes and then have to wiggle or tap control and compressor starts also at time when moving lever to off the compressor keeps running and have to tap control to stop compressor . if you use compressor often spend money and get a square D control

Worked very well. I made one adjustment on the back where each line goes. If not it would not line up correctly. I have used my compressor several times now and it turns off when is suppose to.

Perfect fit in kobalt 26 gal quiet tech.just need adjust to 150psi

Lately the Leco pressure switchies i have instaled have had to be replaced because they leak air between body and mounting. I have had to replace them with the ones i had to buy somewhere else. Now i have been using Leco for a long time and i am surprised that this has happend. It is to late to send them back so i am stuck with 10 I have. Iam dissappored inthem but i will still buy from Amazon

Broke a piece off of my air compressor shut off valve and I had an extremely hard time finding it until I found this valve. It matched up perfectly with my little pancake air compressor. It was easy to install and set up. The instructions were easy to follow. I mean you have to be slightly mechanically inclined to change it but it’s very straight forward. I would recommend this part to anyone with a similar air compressor that requires the shut off/kick valve. It’s an easy fix instead of buying a new air compressor!!

faulty sent back

This pressure switch works well Only issue is that one of the threads on the unit was different than the original one so I had to purchase an adapter. No big deal.
