Liyafy 90-120 PSI Air Compressor Pressure Control Switch with Pressure Regulator Gauges Relief Safety Valve Fittings Set

I needed a replacement asap so I could finish my project. So I order this one. The blow off valve is ok I guess it looks cheap just installed it and it works great only time will tell if it will hold up. Beside the cover everything is all metal I like it a lot

At least it was delivered quickly! The little adapters double as release valves, which is handy if your fittings are stubborn under pressure.That's it for my positive comments.The manifold is brittle, and broke when I installed one of the fittings. I saw other reviews where it looked like they monkey cranked the fittings on, which is obviously a bad idea, but I did the one side and it was fine, so I was surprised when the other side cracked while the fitting was seated yet.The pressure valve is... I'm not sure what it does? I spun it all the way out, and it still releases air to one side of the manifold, at full pressure, and spin it in, and it opens up both sides. There's nowhere for me to know the tank pressure.The gauges are very poor quality. Not only are they wrong (compared to three other gauges I have), but they don't agree with each other!The pressure switch IS adjustable, but there is only one adjustment. I don't know if it thows only from 90psi to a maximum, or if the window adjusts with the max dialed pressure. Adjustment is guess-and-check.

This was a last ditch effort to save my air compressor that my 16 year old son has "accidentally" broken 3 times before. I really didn't want to spend much on my aging compressor so high dollar quality wasn't what I was looking for. I wanted the cheapest I could find in hopes of getting a few more years out of my compressor. This unit did the trick. It wasn't an exact match to the switch on my compressor but was compatible with modding my pressure line. When I u boxed the switch I was a little bit worried. It doesn't look or feel like much compared to the original so I was worried it would fall apart while installing it but proved to be a solid unit and held up nicely to tightening it down. My compressor now has new life and my son is banned from touching it.

If you're looking for a cheap temporary fix then this is the way to go. I don't say this will last forever since there's a lot of plastic but so far so good.

Even though I am using this on a compressor that it was not specifically designed for, it is working perfectly. Great product
