22091 Air Filter Regulator & Lubricator Combo 1/2 inch NPT, 5 Micron Element, Poly Bowl - Compressor Air Filter Air Pressure Regulator Water-Oil Separator Trap Filter, Black/Gray

Good quality

That’s what I need for my air compressor

Little description, unless your a pro of this product, but when it says 1/2 that is for ID , of pipe going in , so 1/2 here is 3/4 OD, so after further review I should of ordered and will order 1/4 ID , 1/2 OD =1/4 here .I guess I should of new that so ordered adapters instead of running in town to send back, ended up being a little frustrating, hope this helps when ordering, if need be .Can't tell you how it works yet , so can't really say if I would recommend. Good Luck, "God Bless Us All" 👍

I passed my return date before I was able to connect this to my air compressor, or I would have returned it immediately. It leaks air out of the top of the adjustment knob. No amount of adjustment, in any direction, even slows the leak down a little bit.

The mounting location for the gauge if you want to flip this unit (so incoming line is on the right and output on the left) is actually cast with a plug in it. This means you can't reverse the unit without disassembling, drilling, and tapping for the gauge and one internal passage as well. This is specified on the packaging as delivered but not in the description.

Leaks at the oil injection part of the regulator with hardly any air pressure!!!

This was a good tool. It didn’t quite fit it for what we need but will put to use.

With a blow gun wide open I got around a 7 psi drop a the regulator which for my purposes is acceptable. The oiler has an easy to see drip viewing glass at the top and the adjustment works as expected. It doesn't leak, the machining looks fine and it works, really can't ask for more at the budget price.
