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

Working great!

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.

Part quality a little on the thin side.

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.

I bought this unit to replace the regulator assembly on an old compressor I got for nothing. I wasn't going to spend a lot of money on repairing it. This was a pretty inexpensive option. At the very least the switch and gauges were worth the price. I first installed it as is out of the box with thread sealer and it leaked in a few places. Took it apart and used the pressure release valve and the coupler from my old unit and used a lot of teflon tape. Made everything as tight as possible without breaking anything and got it together with no leaks. The regulator works but isn't very accurate. It's good enough for what I'll use the compressor for. I didn't expect a top quality unit for this price but it does work and I'm satisfied for now. We'll see how it holds up.

The supplied quick connect hose coupler was the wrong size, it doesn't fit a standard hose connector...USELESS. The supplied shut off valve with the red handle was completely plugged and did not pass any air, full of calcium deposits on one side and the other side showed rust and corrosion...USELESS. The tank pressure gauge butted up against the control housing when screwed on so you would have to remove the gauge to get the control cover off...USELESS. There was no pipe thread compound or tape included...USELESS. When all was said and done, I used parts I already had, yet I had to buy a new correctly sized female quick connect hose coupler. When just one piece is useless, the whole thing is USELESS. This went way beyond. Pay attention to what you are ordering. This was not worth my time and expense.

Unique angle (big win) Second-person POV is rarely explored in gaming content, so you’re immediately standing out. That alone makes it scroll-stopping if executed visually well.

I mounted this on a 1970s vintage Campbell Hausfeld air compressor and it works perfectly. However, it does not come with assembly directions so it is important to take a picture of this ad on Amazon in order to put it together properly.

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…..
