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.

Great fit and easy installation equipment is great

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.

Excellent price, fast shipping

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?

Easy to install and works great

First one was bad but sent back got refund and reorder was a good one
