Unlike another reviewer, I had no problems with air leaks. It handles 100 psi with no leaks. It may handle more, but I did not feel the need to test it at higher pressures then I normally use with my nailers. For nailers that normally do not get used in tight spaces, you can attach it pertinently. For my brad and finishing nailer, as well as my staplers, I put air fittings on one, and put it between the air line and the tool. That way, I can easily remove it if it is in the way. This also lets you use the same oiler on more then one tool.

About the only thing I would like to see is a psi rating on the oiler itself, or at least on the packaging.

Not sure what the pressure rating is on this thing, but it leaks terribly at 90 psi. The acrylic / brass combination just doesn't hold. I tried to tighten up the acrylic part, but the threads slip and it just keeps turning. I'm going for an all-metal inline oiler now. Valley brand 1/4" Airline Oiler. Item No: AIROIL-001.
