This may well be the best regulator I've seen. If I have one complaint, it's that the gauge seems small. That's no surprise, though. It's integrated into the regulator, and the whole block is rather small. Even so, it's a small complaint. Everything is well-marked and legible, and I am most impressed with everything else about it.
I use a 30-gallon, oil-lubricated automotive compressor to run an airbrush. This is probably overkill, but for 5 minutes of noise, I get 2-3 hours of quiet work time. Unfortunately, my compressor has been eating regulators at the rate of one a year, though the last one only lasted 2 months. They work fine at 40 lbs, and may even work well at higher pressures. But sooner or later, when I run the pressure up to 80 or 90 lbs to fill a tire, the thing fails. As you may know, a regulator usually costs $20 to $60. It's a bother.
The regulators I've bought at the Big Box stores seem really cheap. Their performance has been lackluster with several pounds of pressure loss when I actually start spraying. I've had replacement regulators fail right out of the package, too. Not good! With respect to most of the actual failures, I've since learned that it is extremely important to raise and lower the pressure slowly more slowly than I've been doing it. Raising and lowering the pressure too quickly puts undue stress on the springs and seals. But the pressure and quality issues are still a bother, and I still needed a new regulator. So, I chose this one because I-R is a respected brand, this looked well-made, and the price was right.
I'm happy to report that this is an outstanding piece of hardware, and apparently bargain priced. Other sites want $40 to $50 for the same unit. First, this has a very handsome, modular design. Second, all the parts seem well-made and fit together nicely. To adjust the inner range band, you do need to carefully remove the front housing, It snaps off and reveals the gauge assembly. Then, you move the yellow arrows as desired to set your pressure range. You pop the housing back into place and all is good. If you want the pressure knob on top, you remove the housing, remove a couple screws, carefully turn the gauge assembly 180 degrees, replace the screws, and replace the housing. Done!
Once installed, I found the regulator has very little pressure drift maybe a pound or two. Very Happy! Visiting the I-R site, I found that the company recommends putting a dirt & water filter between the air source and the regulator. No stock consumer compressor I've seen has this, and I've noticed buildup of contaminants in a couple of my worn regulators. So, this seems prudent and I will soon install a good filter unit to better protect my regulator.
I recommend this as a very good, bargain-priced replacement regulator. I expect this to perform better and last longer than any other regulator I've tried. I will try to post updates over time. Thanks for reading.

This is a small and light weight air regulator with 1/4 NPT fittings. I'm using it on my home garage compressor (150PSI Max 5.4CFM @90 from HF). It seems to be holding up and doing it's job. I use the setup probably once to twice a week. It is hooked with a filter, T fitting (for full pressure feed to cleaning hose) and NPT quick conects. This is not the type of unit that you want to be mounting to the wall (although you could) expecting heavy use out of. So far so good. I figured for the price I could give it a shot. Also using the Matching filter.. it works as well. Four stars because it is very 'light duty' and feels like I could break it without a lot of effort. This is being use with Air Tools like impact wrenches, rachets and grinders. Could feel a little more solid.

Have been using this for a couple months now and no problems so far. I'm not a heavy user at the moment but basically once or twice a week, so far it has held up. Construction seems pretty decent.
Want Ingersoll Rand R37121-600-VS 250 PSI MAX 1/4-Inch Regulator, Black Discount?
I bought a cheap compressor that had a cheap regulator. The regulator would drop pressure by at least 20-30 lbs as soon as I turned on the air tool. I replaced the regulator with this Ingersoll Rand regulator. It now only drops less than 10 lbs when I turn on the air tool. It drops pressure because I have a water filter down the line which is a little restrictive. I highly recommend this item for a small compressor.

I installed this regulator on a Rol Air JC10 after the factory regulator broke. It is quite simple and just has an in and an out port that fits 1/4" NPT connections. The built in gage works just fine, but is a hair on the small side. Being that the unit is compact, there isn't much way around that though. You can switch so that the adjusting knob is on top by switching the gage to the other side and flipping it over. It just requires removing a few screws. The adjusting knob clicks in and out to lock and unlock. The gage has an upper and lower yellow band that you can set to the desired value. This can help so you don't have to get close enough to read the small numbers. I would buy it again. It feels solid and works great.
Very nice product over all. Had a couple minor problems with things, Contacted company, they fixed it in a good amount of time. The best thing i like about this is that Tool Price, ( the company that shipped this DA Sander) is unlike most that have a pre printed letter to send with, this was hand written (not a copy of it, I find this rare of any company, and Fixed the problems that had happened. Great work Tool Price and thanks for the fast action on getting things fixed. Also looking forward to looking at more tools of your guys.
