QWORK Air Compressor Pressure Switch Control Valve, 90-120PSI Pressure Regulator with Pressure Gauges Fittings Set

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.

Came in pieces. The Air Hose quick disconnect is Crap, without adjusting anything, just install, it came apart in my hands even without adding air pressure, otherwise came without instruction, but I figured it out and it works... I would like a refund on the quick disconnect as it is no good... Give me a refund update within 3 days...

Part quality a little on the thin side.

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.

My husband said this worked for what he needed.

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.

Regulator’s been installed for a couple weeks now and has worked very well so far. Assembly instructions would have been nice but it’s not too hard to figure out

Product is quality replacement part. Durable. Great product.
