LF10-4H

I was weary to purchase this product because it was exactly like the one I had and it failed by leaking air. SO far this controller has done its job and I hope it last longer then the one it replaced. The price was very good for this item.

Bolted right up

I ordered this pressure switch because my air compressor was continually leaking air at the switch. The on/off lever was different than original but I was able to loosen the four screws that attach switch to the base just enough to get lever out (with out losing spring) and I swapped it with original lever from old switch. After installing this new switch, it was leaking air too - again at the unloader valve. I then discovered that the switch wasnt the problem. It turns out the check valve on top of the tank was leaking. I removed, cleaned and replaced the check valve and that fixed the leak. The switch works fine. It only required a little adjustment to get it to shut off at the correct pressure.

Easy to hook up and adjust, wiring and pressure adjustment are on the inside of the cap. Would buy again.

product is exactly as represented. not sure why i need more words but apparently more words are required for a rating?

They should ship this with adjustment instructions. There are two adjustment screws, one for the cut out and one for the differential. They are not marked and there is nothing to tell you which is which. Dont get me wrong, you will figure it out, but it would be nice to have an instruction sheet with it.

Works great.

Product part number matched existing unit, however, the pressure sense line was incorrectly located making this switch incompatible with the compressor. Make sure your unit matches precisely or it wont work/fit.

Great price. I was able to resurrect several compressors with this part, as I ordered three of them. All worked perfectly.

This is just exactly what my husband was looking for. It fixed the problem and he is back up and going
