PneumaticPlus PPR3-N02BG High Flow Air Pressure Regulator, 1/4" NPT

Worked as advertised and allowed for enough CFM to blow out my sprinklers while maintaining safe line pressure.

Update: I got in touch with Pneumatic Plus support which diagnosed the problem with me and sent a replacement. The replacement is working fine so far, so I’m revising my rating. I’m happy with the product and support. ========== Original review: Given the premium price, I bought this thinking it would be a higher-quality part. Two months on and it slowly drains the compressor tank if left on anything other than the highest pressure setting (i.e., the same pressure as in the tank). This was sold by "Amazon.com Services LLC" and the return window closed after 30 days. There's no way to contact Amazon about this, and no information whatsoever on contacting the manufacturer. Really unhappy about being out the money and having to repair this once again.

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.

Accurate, works inverted, easy to read and accurately displays pressure drop. A great addition to keep tools healthy with high flow footings.

This was a breeze to install, perfect replacement for my 13yr old regulator. Works well, been using it about 60 days now full time in my machine shop.

This thing leaked right off the bat. That was the whole idea of the purchase. My compressor cycles constantly due to this piece of crap. Having put up with this for a couple of months, wanted to return, but too much time passed for Amazon to do this. Poor quality

Use this on our edge bander to lower the air pressure on the glue station.

The item performed well and built sturdy.

Easy to install quick delivery great price.

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.
