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

Works as intended, no leaks, running 150 psi

This is a solid regulator/filter, it's accurate and easily adjusted. The one thing that I LOVE, LOVE, LOVE, about this regulator is the fact that you can mount the gauge on either side. When I first bought it it hit me. I thought, "Oh no I forgot these always run with the flow left to right so the gauge is going to be backwards!" Luckily because of its design this wasn't an issue. It has a nice deep polycarbonate bowl just like an expensive ½ regulator. As far as catching water it does its job just as it's intended to. One thing I didn't like is the cheap gauge that came on it, so that's one thing I replaced (as seen in video). Overall for the price you can't go wrong. It seems to be durable enough and installation was a breeze. As far as compatibility it was completely compatible. A great purchase for sure!

Fixed my compressor's leak problem. Well not 100%, but the remaining leak is very slow and is likely happening elsewhere. I'm good now, because my compressor might self-cycle once every hour as opposed to once every 5-10 minutes. For my occasional use, that's totally acceptable. I did have to dismantle more than I was expecting, because my pancake tank didn't have enough clearance to directly attach this. I had to remove the main assembly and gauge to be able to screw this in. Others commented about a lack of instructions. Mine has an arrow on the back that showed the direction of airflow, and it does not seem to leak air.

This is a nice upgrade over most common inexpensive regulators. I would buy it again if need be. It seems to be nicely made and is easy to adjust. I have not tested the flow but assume that it meets the specs. The regulator comes without the gauge installed. There is a cap in one port and a plug in another. Half the users could remove the cap and screw in the regulator. The other half will want to move the plug so that the regulator can be installed upside down or configured the input on the right. It takes a 5mm hex wrench to remove and replace the plug. As for installing the gauge, it is needlessly difficult because there is not much space between the body of the regulator and the back of the gauge. What is needed is about a 1/2", thin profile open end wrench. Thin profile means less than 1/4" thick. I was hoping to find one in my set of ignition wrenches but they only went up to 3/8. My smallest adjustable wrench, with a handle less than 4" long, was still too big. I ended up doing it, barely, with an old pair of needle nose pliers. After installation I changed my mind and wanted a different fitting on one side. In the process of cleaning up the threads it became obvious they come from the factory painted. I would prefer bare aluminum but maybe this is a zinc casting or something that needs corrosion protection.

I was a bit leery when purchasing this, however, after fairly long use, it still performs as advertised.

Do NOT buy the piggyback unless you want a leak within a week. My five star review is ONLY for the regulator. I tried the piggybacks and they all developed a leak where valve is installed in the bottom of the bowl in less than a week. 0 stars for the piggyback. I tried some cheaper piggybacks/regulators and the gauges are trash, you have to tap them to get the current air pressure, not on this one! This one is very responsive whenever you make any adjustments. I am currently installing one of these or this with the added filter/moisture trap (for only $8.00 more!) at every wall manifold/drop in my garage. (I am leaving the drop on the ceiling unregulated) if I need to use any pneumatic staplers, nailers or blow guns I have the ability to adjust the air pressure to perfectly suit the tool I am using at whichever drop I am at. I used some T-nuts I printed on my 3D printer to mount the regulator to the Gladiator wall panel and used various brass hardware to route the air from the manifold to the regulator for a rock-solid, no-leak, regulated compressed air hookup. The output has a 90 degree elbow and a Milton 5 in 1 1/4” NPT quick coupler.

Did not last six months. Regulator failed, adjuster failed, just sat there and leaked air. Yes, I had a water trap and a filter immediately upstream. Bought a different replacement make from Lowe’s. It too failed after less than six months. Going to buy an all metal Parker (the real USA made Parker, beware the China copy sold here on Amazon with “Parker” in its name). I can’t risk all these cheap plastic regulators failing and ruining a paint job.

It seems to be well built and is easy to install. The instructions are in Japanese primarily, but also come with English as well. Reasonable price compared with other products that are similarly spec'd. I tested it multiple times without any leaks or issues. I have the psi set to 125 lbs. which is more than enough for what I'll need it for. e.g. tire inflation, air tools, plasma cutter etc.

Good build quality

Nice build. No leaks. Precise pressure hold.

​サブタンクに空気圧調整機能を付けたくて購入しました。 思った通り、しっかりと正確に圧力調整ができるので満足しています。 ​注意点として、メーターなどの部品は自分で接続する仕様になっています。エア漏れを防ぐために、あらかじめシールテープを用意して組み立てるのがおすすめです。

Works as it should.

As described, appears to be a very good casting and good machining, it appears to be well worth the money. Only complaint is the gauge, it's threaded undersize and I couldn't use it as it would bottom out on the wrench flats before tightening up on the threads even using teflon tape. I ended up buying another guage, it was definitely the gauge that was machined wrong as I tried multiple fittings in the regulator and they fit well. I also tried the gauge in my old regulator and it would bottom out on that as well.
