Master Airbrush Heavy Duty Premium - True Diaphragm Mini Regulator with Gauge and Water Trap Filter, Fits Airbrush Compressors

I bought this regulator to assist in keeping the airflow to my airbrush consistent and easy to change on the fly as the regulator is now close to the spray booth. This thing resolved an issue I was having as the compressor's tank became full the pressure at the airbrush slightly dropped or was inconsistent for a few seconds during this time. This resolved the issue.The only thing I wish I could change is the orientation of the entire block to swap the incoming and outgoing ports, or change to port that you attach the pressure gauge to. Other than that, a fine product that is easy to use and keeps the pressure consistent. Super happy with purchase.

This was a perfect upgrade for my compressor which only had a pressure gage and moisture trap. Now I can have a regulated air pressure of 20psi for my airbrush. One note: I had to use an o-ring to ensure a tight seal of the pressure gage in a face up position; without that o-ring, the gage was timed to face downwards at full seal.

Bought this regulator to replace an old one on a Sparmax compressor. The item arrived quickly but condition is just acceptable, the four screws at the corners were slightly rusted. Set up was supposed to be straight forward but the fitting connecting to the compressor was not a perfect seal. Needed to use quite a bit of Teflon tape to fix the leak. Other than that, it works fine, decided to keep it.

This replaced a regulator that failed on a Vivohome compressor/tank. It's an exact fit, and worked as soon as it was installed. You'll need teflon tape to install this correctly.The other thing is, this is a high-quality item. So is the Vivohome compressor...I have no idea how the original regulator on it broke.

Perfect fit and works great

I bought this because it was cheap. Sadly, it had a huge air leak in the water separator/drain. Also, the air flow valve would not adjust. Package was open but sealed in an Amazon bag when I received it.

Pipe threads are governed by two sets of standards: National Pipe Thread (NPT) and British Standard Pipe (BSP). These standards stipulate the types of screw threads used to connect and seal pipe fittings together.The NPT standards are divided into two categories: National Pipe Tapered (also NPT) and National Pipe Straight (NPS). Likewise, BSP standards are separated by tapered (BSPT) and parallel (BSPP).Tapered threads use thread sealant to archive a seal where as straight (or parallel) need an O-ring or a gasket to create a tight seal.NPT/NPS and BSP threads are not compatible due to the differences in their thread forms, and not just the fact that most sizes have a different pitch. NPT/NPS threads have a 60° angle and have flattened peaks and valleys (Sellers thread form) where as BSP threads have a 55° angle and have rounded peaks and valleys (Whitworth thread form).Pretty sure this regulator is BSP threads. America's 1/4th" NPT/NPS threads have like 18 threads per inch. 1/4th" BSP threads have like 19 threads per inch. So depending on how you are using this regulator, you may need O-rings or thread sealant to make it work. I used standard American NPT 1/4th" air fittings with lots of teflon tape and it worked ok.I plug the regulator into my air compressor, then my 50' air hose, then my airbrush hose plugs into my 50' air hose. That allows me to get far away from the loud air compressor. Enough threads screwed into the regulator to make a good seal for me.

You may or may not have the same issues I had. I’m not a novice to airbrush, I’m an artist and have a workshop. I purchased this because my regulator cracked over time and was leaking air consistently. It’s very easy to install, basically plug and play. It was leaking air from where it screws into the compressor, where the pressure valve connects and where the airbrush valve connects.I needed to install rubber washers to prevent the leaking. Then I noticed another leak. Where the unit comes together in the center (sorry, I’m not sure what to call it). But I had to remove the 4 screws that hold it together and place Teflon tape around the inside on all 4 sides to give it a proper seal. As you can see in the photo. THEN it finally worked correctly! Being that I have 7 orders waiting to go out, I don’t have time to send back for another. Luckily I’m a handy person who is a problem solver because I don’t think my husband would have gone to the same lengths to fix it. Now that it works, yes, it does it job. But I honestly shouldn’t have had to fix a brand new item. Silver lining is that I can finalize my orders for Monday shipping
