PneumaticPlus PPR3-N02BG Compressed Air Pressure Regulator 1/4" NPT (High Flow), Embedded Gauge & Bracket

Bought this to improve air control on my airbrushes. Sometimes I need to use very low air pressures. The regulator on my compressor was impossible to adjust below 10psi with any repeatability. I bought the 3 to 30psi version and put it downstream from the air compressor regulator. I located it so it is at hand while I'm painting. It works beautifully at ultra-low pressures with my .2mm detail airbrush. If you are getting one to use for this purpose be advised that you may have a problem finding the correct adapter. I needed to adapt the 1/4" female NPT on the regulator to the 1/8" BSP thread used by Iwata and many other airbrushes. So, I needed a 1/4" NPT male x 1/8" BSP male adapter. After searching the internet for 2 hr. I decided no one makes such an adapter. I ordered some 1/4" BSP male x 1/8" BSP male adapters. The 1/4" BSP threads are close enough you can get about 3 threads engagement into the regulator and maybe get it to seal with a lot of teflon tape. I decided to chase the threads on the adapter with a 1/4" NPT die. I was able to get full thread engagement but it still took several wraps of teflon tape to get a good seal. Installing this in my system was a PITA but well worth the effort.

I use this downstream of my onboard air to inflate tires to a chosen pressure without having to hold an inflator trigger the whole time, or risk over-inflating when attaching a hose directly between the compressor and tire. I've put a female coupling on the output, so to set it I plug in my inflator (with gauge) and dial in the pressure I want, then remove the inflator and replace it with a T, two hoses, and two Haltec H-5265 chucks to two tires. This lets me air up two tires at a time relatively unattended and make sure they all have the same end pressure after off-roading (15->50psi), plus makes it easy to bring up the pressure further in the rear two tires when needed for heavy towing (50->80psi).I've only used it a handful of times at this point, but it's holding up well so far, including being put loose in a bag with other air-up parts and not handled particularly carefully. Since I'm using a simple onboard air system I don't have an air filter and dryer upstream of this regulator, so I don't know how long it will last before the lack of filtering causes any problems, but no issues yet.

I bought this to use with my pressure gauge calibration set-up for calibrating the gauges at a brewery. My old regulator "drifted" far too much, making it very hard to calibrate a gauge. This one works quite well and is stable once you get it to a desired pressure. Ports are the right sizes and locations for my use. This is a relieving gauge, so if I overshoot my desired pressure it's just a matter of backing off a bit.In the photo, the digital calibration gauge is to the right, gauge being calibrated left, on the regulator, and air in far left.

I purchased this regulator so I could modify a tool for low pressure evaporative emissions testing on vehicles. This regulator is very good quality and can handle extremely low pressures with no problems. One thing I would suggest for future development is to shrink the size of this device, the knob is way larger than it needs to be as well as the body of the valve. For my specific purpose I wish it was smaller but it works perfectly.

This 0 to 30 Psi regulator and pressure gauge, is Perfect for my airbrush setup.My set up is...Air compressor > hose > filter > this valve/pressure gauge > airbrush hose > airbrush.It really makes a big difference, being able to dial in these lower pressures, more accurately.Good quality, I would buy again, if I add another airbrush.

Bought this as a regulator for my IWATA Eclipse airbrushThe regulator for my high speed engraving tool was the wrong range (0-100) - not sensitive enough in the 10-20psi range required for the airbrush -this regulator is 0-30 psiOperation seems stable (no variation in pressure output) - so far so good.Happy with the purchase

Perfect for portable air tank. It with the elbow (see my other review) allowed me to mount all the pieces within the tank's dimensions. By the way, the Kobalt tank is the only one (that I found) that will accommodate this kind of a setup.

I use this to reduce compressed air to run model steam engines. It works flawlessly and has been doing so for several months of use. It is well made and accurate. I have been through three other regulators before I found this one; happy that I found it.

Not too much to write about. It's a regulator and it regulates pressure like it is meant to. It is a low pressure regulator and I purchased it to make a pressurized brake bleeding set-up. It works beautifully and one person can now bleed brakes in about 5 minutes or so. Paid for itself on the first brake job.

This came with a 0-160 PSI gauge as opposed to the advertised 0-60 PSI gauge. Avoid buying this product if you need precise measurements.

It is working well. The only reason I gave it a 4 instead of a 5 is that the pressure gage readings are a bit small and a bit hard to read. But not a deal-breaker.

Works very well, I can accurately adjust right down to nearly zero and it will maintain with very little drift.

Great little instrument type regulator.
