SNS AR3000-N02 Female Thread 1/4 NPT Air Pressure Regulator 0-150 PSI Adjustable,Bracket,Gauge

I'm impressed with the SNS AR4000-N04 air pressure regulator! It's a great choice for anyone who needs accurate control over air pressure in their projects. Here's what I particularly liked:Easy Adjustment: Setting the desired pressure is a breeze. Just pull up the knob and turn - simple! No complicated instructions or finicky controls.Precise Regulation: This regulator delivers consistent and precise pressure within the 0-150 PSI range. No more guessing or wasted time with imprecise adjustments.Built to Last: The aluminum alloy body feels solid and durable, giving confidence it will withstand regular use in my workshop.Ready to Use: The included bracket and gauge make setup a snap. Everything you need for installation is right in the box.Great Value: This regulator offers excellent performance at a competitive price. It's a smart investment for any workshop or industrial application.Overall, the SNS AR4000-N04 is a dependable air pressure regulator that's easy to use and built to last. Highly recommended!

Nicer than the one that I replaced. Solid construction.

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.

Seems to be a good product. Will see how it stands up to every day use.

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 .

After spending enough on my compressor I didn't feel like spending hundreds on a regulator so I bought this 1//2 inch one for thirty eight bucks. It is working fine maintaining 90 psi with an air grinder while provided with 175 psi on the intake. The plastic bowl is protected by a metal shield that comes off with a push of a lever and a twist. Inside the bowl is a sponge bronze filter that is held on by a plastic nut that you turn to take it off and hold it in place.The bowl itself has an o-ring at the top to prevent leaking. The regulator comes with a 1/4 MPT gauge and a bracket that I didn't use, with screws. I had a problem with leaks at first but I don't think it is the regulator's fault. The 1/2 inch pipe threads are about an inch long and seem to have a taper. The problem I had was with the hex nipples. They do have tapered threads but not consistent and not long enough. I had to select the side with the most taper and screw it into the regulator all the way until it bottomed out in order to stop the leaks. I have used 1/4 inch nipples like these and have had the same problem I don't allow any leaks in my system no matter how small. I included a photo of my hour meter that I set up using a project box that I also bought on Amazon. The meter is wired in parallel with the motor. I am satisfied that the regulator will do the job it is intended to do and have given it five stars.

Good product well built

Installed too late to return it but it leaks under the knob so please don’t order this. Unreliable and low quality.
