PneumaticPlus SAR400-N04BG Compressed Air Pressure Regulator 1/2" NPT - Bracket, Gauge

Small and compact.

It worked as stated, I have it on my AIRCOMPRESSOR, it works GREAT!!

Update 10/19/2022: I contacted the company and spoke with Richard who wanted me to check and see if it was installed backwards (air flow). I was pretty sure that was not the issue since I just piped my garage and installed two other filter/regulators without any issues. Well, went home and checked it and sure enough it was installed backwards. Switched it around and pressurized the system and all is good, no leaks. This does seem to be a well-made product and I expect it to last quite a long time. Customer service is what usually separates one company/seller from another and they were quick to respond when contacted. I'm glad it was a simple fix and I didn't have to go through the returning or refund to purchase another one.Purchased this for my home compressor that I just completed the max line install. This thing leaked from day one. I lowered the pressure and locked it down which stopped the initial leak. This system isn’t used much at the moment so a few weeks went by and today I aired up the compressor and this thing started leaking like crazy. I guess I’ll try to contact the seller and look into a refund or replacement. I know there are always bad items no matter who manufactures something so hoping this isn’t a real quality control issue. We will see how this goes. I’ll post back if this gets handled or not.

Works well and is accurate and strong. Adjustment is smooth.

Everything fits nicely, the brass 1/4" nipples I bought worked perfectly with it. By the way, I have found that yellow plumber's tape, the one that says it's for gas lines, gives me the best seal. I am reserving my judgment on this device because it was difficult to get it to hold pressure down to 90psi. This is what my impact driver says to use. I want it to go as low as 60 psi. but no luck yet. I am going to check in with the manufacturer. The locking cap works perfectly, while the mini, 1/8" fitting, gauge is a little small for my eyes, it is the perfect size for what I am using it for. Trade-off here. The regulator on my other compressor works with no problem to all levels. So I will let you all know how it goes.

I liked the quality and the ease of replacement of this regulator. It is easy to adjust to your desired pressure.

Replaced faulty regulator on a 20 year old Harbor Freight 10 gallon compressor. This regulator knob sticks out a little bit further than the original, but fortunately, you can pull the knob off to install... get it oriented correctly, the push the knob back on. Also, you can lock the knob position by pushing it in till it clicks... This apparently keeps vibrations from moving the knob. The body is made from some type of cast metal. The knob is plastic. Does come with a adjustable mounting bracket. The included pressure valve is NOT liquid filled.

The gauge port size on this regulator is 1/8" NPT but MOST 3/8-inch regulators use 1/4-inch so the better quality gauge I bought didn't fit. (The one that comes with it is pathetic!!) PLEASE list ALL port sizes for your pneumatic equipment so we can plan for the right stuff instead of guessing (especially if it's not standard)!!!!
