Review on Secbolt Horizontal Air Compressor Pressure Switch Control Valve 90-120 PSI - Efficient Manifold Regulator Gauges by Kory Shelton

Edited on June 21, 2018 and downgraded to two stars. That was two months before the crash. I found I couldn't get my blood pressure above 20psi despite running and running. My first suspect was the compressor, which I also replaced the piston, gasket, etc. He pumped out a lot of air. There were no leaks. Checked by removing the steel line to the tank and yes, LOTS of air. But the distributor was not working properly or the sensors. Who knows. All I know is that the compressor works great, the lines are clean, no assembly. Why should I do this? Since I NEED it now, ASAP and for $30, I'm going to risk it and allow myself to buy a good one elsewhere. If you're not in a hurry, don't skimp. But if you need it LIKE TODAY, it really works and I've used it a lot. It worked well and my compressor is happy. Just some thoughts to help other customers. The product is delivered disassembled, no instructions. It is best to look at the picture and compare the items. A few notes One gauge with a LARGE thread goes to the pressure switch box The other goes to a 4-way regulator, but BEWARE. 3 sides have 1/4" NPT threads and one for a smaller gauge. So that will help guide the left hand CASES into the box as you tighten them. So if you're using the straight up and Can't get a down-facing gauge you can get an extension nipple I couldn't use the air hose connector that came with it (I use type m) so I used my own never mind the whole device seems a bit cheap BUT I do have to say it worked great, accurate with the pressure settings and following the instructions in the box I turned the pressure off and lowered it to around 100psi.
