QWORK Air Compressor Pressure Switch for Pneumatic Tools, 90–120PSI Adjustable Controller

Works like it should. I had to do some reconfiguring for my use.

So far good. Purchased this for an old 20gal 125psi max compressor that had a faulty pressure switch and no longer switched off when it reached the desired pressure. Doesn't come with any instructions, but does have a wiring diagram on the inside of the cap. Ended up not using the smaller air valve, hose connector and pressure relief valve as they were of much lower quality compared to what I already had. Between the new part and my old part, I had enough parts to make the repair. This kit doesn't come with any thread tape, so have that purchased ahead of time and ready, you will need it on ALL threads. Doing this, I had ZERO leaks.

This item is quite good especially for the price. The only reason I'm giving it a 4 star is because there ŵm was zero documentation in the box. I'm mechanically inclined so it wasn't difficult to figure out how to install but adjusting the on and off pressures was a bit of a challenge to figure out. It's possible that this was an Amazon return and they sent it to me at full price. (Total BS if that's the case but it's happened before) I will attach a picture of the box so toy can see what I'm referring to.

Definitely keep a picture no instructions at all.

Working great!

Works fine so far. You can tell just by looking and feeling most the parts are cheap. I couldn't use a few parts because of that reason.

Please don't waste your money on this one, let me explain. I suppose somewhat my fault for trying to save a couple of bucks. This thing is not worth the postage that it took to get here. Got it installed and wired, filled up my tank and I could hear a hissing. Tracked it down to a gauge and tightened it. It was still hissing. Tightened it down some more, still hissing. Turns out the gauge had an internal leak making it useless. Not the end of the world I had another gauge so NBD. Upon tracking down another leak, it was the regulator. The entire regulator body was cracked. Now this isn't my first rodeo with these types of things, but the regulator body was as cheaply made as it could possibly be, and I suspect it cracked during installation.. So let's assume that's my fault but next on the list is the unloader valve. It does not function properly. One flaw, I can overcome but three on the same job? I don't think so. As I'm typing this, I hear the pressure relief valve leaking as well. I even have another one of those but by this point what did I actually buy?

Everything was as listed. Our first delivery was a sweatshirt instead of compressor parts. Too complicated to send it back so I just kept it, but Amazon immediately sent out correct parts.

Instalado sin mucho problema, apariencia ruda pero funciona correctamente

Facile da montare!

Facile à installer, fait le job, réelle impression de solidité à confirmer dans le temps

All the components you need in 1 package. Great price. Works as it should. I dont know what the little needle valve is used for.

Arrivé en pièces à monter soi-même. Ce n’est pas un souci, je suis bon bricoleur mais pour les autres ???? Pas de notice. Au montage, ne fonctionne pas correctement. Pas de contrôle de la pression. Je dois l’arrêter manuellement. Le ressort interne n’était pas attaché. Pour éviter un retour, j’ai essayé de réparer mais ce fut une mauvaise idée. Difficile à remonter. Un peu déçu…..
