This worked perfectly!!
This worked great !! I bought 2 others , one from Home Depot and another from Harbor Freight that didnt work at all . This valve could adjusted by lifting the knob and turning it til you reached the desired psi , then pushing the knob down (locking it) . The others were not true regulator valves . If you turned them to regulate the pressure they would let the air out of the compressor tank until it was at the pressure you desired , the only problem was that the compressor would then run non stop .

Good Quality
Replaced a cheap OEM regulator on my air compressor. I had to disassemble the new regulator in order to screw it on to the existing pipe stub, but it was not a big deal. Regulator has been successfully working now for over one year.

Excellent product.
Works great with my stand up husky compressor.The valve that came with it started leaking and this did the trick.

5-Stars, With A HUGE Caveat and Why It "Leaks"
The 5-stars are ONLY for the functioning of the regulator itself. See below for what I think of the manufacturer, the seller and the provided documentation.This Regulator, 5-Stars: This regulator functions well with plenty of air flow. It's easy to adjust and holds its set pressure very well. It does not leak, with this caveat: When installed correctly! No doubt many others have returned this regulator because they have installed it backwards, which causes it to leak and hiss under the adjustment knob. Meaning, it has been installed with the compressor air-flow going into the OUTLET port and the air hose hooked up to the INLET port.The Manufacturer, 1-Star: The regulator I replaced, and others I looked at, had markings showing the direction of air flow embossed into the casting. This one does not. Meaning, you have a 50/50 chance of hooking it up in the correct direction. In my case, my compressor's air flow moves from the piston on the right to the air hose left. I had to remove the 1/8" NPT plug from the opposite side of the regulator and install the pressure gauge on that port. And then install that 1/8" NPT plug into the port with the orange rubber plug.The Seller and/or Manufacturer, 1-Star: NO INCLUDED DOCUMENTATION. If either one had simply included markings or a sticker on the casting, or included a sheet of paper with a diagram showing the direction of air flow, I am positive there would be a lot fewer returns for "leaking and defective" regulators. Me included.After dealing with these issues and finally finding the included diagram from the Amazon product listing page, I got it to work perfectly.
