      Worked good at first but the oil camber leaks air. The o-ring seems to not seal even though it isn't tore after a couple weeks. I just have to replace the o-ring I think.

    Questions & Answers

    • Q:

      "Is this a proper product for use in spray painting?"

      • A:

        This particular item is a regulator and a water separator which would be good to use with a paint gun but it is also is an end line oiler air tool which will lubricate and the lubrication may mix with the paint, we do not not suggest using this item with your paint gun for spraying automobiles.
