NANPU 1/4" NPT Compressed Air Filter Regulator Lubricator Combo Water/Oil Trap Separator - Gauge(0-150 psi), Poly Bowl, Semi-Auto Drain, Bracket - 3 in 1 Two Unit

It works okay, easy adjustment, installation was easy.

Dependable, and easy to install. Prelubes air tools. Easily adjustable.

Product works good but not really impressed with the plastic fittings

So far so good. I haven't used it enough to know if the water seperator works but the oiler does. A matter of fact maybe to good. You can literally see it dripping oil into the line and I have to keep it barely cracked open otherwise it dumps way to much oil in

this needs some assembly but by doing the assembly yourself it will get done right.

works great great price

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 !
