VIAIR Pressure Switches

Works at the psi's indicated.

I have an air compressor mounted under the hood of my truck that is connected to an air tank in the back. This pressure switch allows me to leave the compressor on for long periods of time and not worry about building up to much pressure and damaging my air compressor

Works as described, and is actually a pretty good price for a relay and a pressure switch. The bad thing is that they absolutely hate water. I'm on my third pressure switch/relay in less than two years. I'm going to change the mounting location and seal the thing up with silicon this time.

This pressure switch works just as advertised. On at 85 and off at 105. I combined it with a one gallon Viar tank and a Quick air compressor, added a simple bosch relay and everything works great on my Jeep. I can easily air up tires and use simple air tools. Great product.

I'm using it to turn control pressure on an MV50 pump. The pump can blow seals if you don't turn it off before it builds too much pressure, this pressure switch works perfectly, It thread directly into the cylinder head, and the wires were labled with how to hook them up. Turns on at 85 and off at 105. I picked this set of pressures because they should work with an ARB that I plan to add later.

works great as coming from a quality company "VIAIR" just wish the 1/8NPT fitting was 1/4NPT.
