COMPSTUDIO 110-140 PSI Air Compressor Pressure Control Switch Valve Horn 1/8" 12V/24V - Heavy Duty for Automotive, HVAC & Industrial Applications - Perfect for Air Tools, Tire Inflation & Pneumatic Systems

I purchased this switch for a dual piston 12v compressor i use for my 4x4 truck. When I air down or air up I use the compressor. This compressor has no tank and is just to fill tires. so bought this pressure switch and put it on a small brass 1/8" threaded manifold with quick coupler connections, and wired it with a SAE plug, so my compressor 12v plugs onto the switch, the switch has several different connectors for 12v, SAE to my camper rig, SAE with alligator clips for the battery terminals.i quick connect the compessor to the manifold plug the compressor into my pressure switch and then plug the other 12v end into my 12v SAE on my truck camper. After plugging in the air quick connects to the compressor I then quick connect the other end into a portable 2 gallon pressure tank. So the compressor will now turn on at 90 psi withing a few pounds of that and then turn off at 110.If i do not use a pressure switch I have to be careful as the compressor will run up to 160 PSI and not stop running, there is no cut off on the compressor, it is a large twin piston compressor and comes up to Pressure extremely quick. The switch is the perfect range for my pressure tank, does not run the compressor up to its max at 160 psi and again no cut off, the pressure relief valve just pops off. So the switch is such a easy and quick fix and very convenient to use and stores away very easy with the compressor and air hoses. I would recommend this pressure switch, it works well, it is not precise to the actual 90-110 psi, but it is consistent where is starts and stops within 1 psi.it is 10 psi less than my air compressor max pressure however my air compressor is working again.great productGot it the next day and work like a charmNeeded a replacement valve for my VNL Volvo and dealer wanted 45.00 dollars for near identical valve. This valve is working just fine for me and I recommend it and the seller. I'm quite pleased with both.Used to fix my Kobalt air compressor. Works great. Tank pressure reads 155 when it shuts off, buy I think the guage is off. Easy fix and price was great.Works goodWorks great as replacement on my pancake air compressor. Rerouted the air line to accept the scew in style.
