Adjustable Oil Pressure Switch Sensor 765754 76575-4 4D-4785 1/8-27NPT Highest to 7 PSI Normally Open for Hobbs Honeywell M4006-4 Caterpillar CAT 2Y-4439

Tested and works perfect. Was able to adjust on psi.

The brakes lights were not turning on when I pressed the brake pedal on my diesel pusher motorhome. The two original pressure switches were not closing so I replaced them with two of these switches, since they have the same 4 psi trigger threshold. I had to use a 1/4" to 1/8" NPT adaptor pushing ($6 on Amazon) to fit the 1/4" threaded opening on the brake pedal. They work great so far. Time will tell how long they last.

just what i needed to replace switch on an old tractor rebuild.

The mounting 1/8" pipe threads fit exactly. This was my biggest concern. The failed switch I replaced with this one had an integral ground that worked through the treads, but this one has a separate terminal that I wired directly to ground. I liked that because proper grounding is assured. I bench tested this switch for activation pressure and saw it go on at exactly 4 psi as advertised. Great switch and is priced right too.

Used it on a generac generator and it worked

I’m using this for the methanol injection kit on my audi and it works great. The threads are hard to find fittings for so I just re-tapped the end of it to a more standard thread that I could find fittings/nuts for. Way cheaper and wayyyy higher quality than the crappy plastic switch that came with the snow performance methanol kit. This one it actually solid and feels really nice compared to that one

worked

wouldnt buy. shouldve bought the right part name brand and had my generator up and running last year

Excelente producto,

It works

I purchased this to replace one leaking on my engine in my boat. Works great at a good price. Gonna order a second one for the other engine.

Lo use por que el fabricante de la cadera no tiene refacciones y este producto, reemplazó a la perfección la pieza original.

Used on my diesel engine oil light.
