NANPU1/2" NPT Compressed Air Filter Regulator Lubricator Combo Water/Oil Trap Separator - Gauge(0-150 psi), Poly Bowl, Semi-Auto Drain, Bracket

I wanted to adapt an air compressor with a three-gallon air tank that I use for pumping up tires in order to operate a recently purchased airbrush. This air pressure gauge and moisture trap will ensure that air powering my airbrush will not be contaminated.

Works as it should. Seems to be good quality. Been using for over a year with no problems.

The plastic water separator bulb cracked after less than 3 months of use. The company that sells the item reached out after a bad review was given and offered to send a replacement part free of charge. Hopefully the part lasts longer than the original. Yet to be seen. Rerating from 1 star to 4 for product support.

As advertised and it came with all necessary parts. Has been working perfectly since it was installed.

Fast delivery,easy installation and working as expected.

The machined 1/4 nipples that come with it were a little too loose in the thread housing of the regulator so I used A LOT of Teflon tape to get them snug. Also the Teflon tape that comes with it is cheap. I used store bought Teflon tape. Once hooked up I decided to press in the manual drain at the bottom of the water filter cup to drain the water (while the regulator was under a load. BIG MISTAKE, the o ring that seals the drain got bound up in a hole on the moisture drain plug and was then leaking while in the closed position(the purpose of the horizontally drilled hole in the drain plug I'm not to sure). I had to disassemble the water trap remove the C clip holding the drain plug pin in place and very carefully use a pick to fish the O-ring out of the hole in the pin. It was a pain in the butt because the parts are so small. Doesn't do a good enough job filtering water either. I'm constantly blowing out water mist from my tools. Also the housing of the oiler bottle has a leak because the outside of the oiler is always, well... oily. Water gets in my oiler as well defeating it purpose. With the oiler turned on it doesn't distribute oil to my tools it just puddles up in the coupler coming off the oiler. This may be because I have high-flow couplers and high-flow male plug fittings instead of your normal fittings, I don't know. Also the pressure gauge is not accurate. I had my suspicions so I attached a high end glycerin filled gauge to the end of my air hose past the regulator. I set the regulator to 90 my pressure reading on the gauge at the end of the hose was nearly 100psi. To be sure I also hooked up a secondary regulator past this regulator and opened it all the way while setting the purchased regulator at 90 psi, same reading on the fully opened regulator past this one at nearly 100 psi. Also the increments on the pressure gauge don't make sense. Instead of normal 5 or 10 psi markers on the gauge this one goes in increments of like 7 or something close to that, which is weird. But hey you get what you pay for right?

Great water trap got zero flow thru oiler, disconnected the two am using water trap only.

I like it because it has the oiler.
