Devilbiss KK-4987-2 Spray Gun Repair Kit - Replacement Parts for Devilbiss KK49872 Paint Sprayer - Perfect for Automotive, Woodworking & Industrial Painting Projects

Pretty good kit. Some of the parts are not a perfect fit, though. The o-rings supplied for the air adjusters were a tiny bit smaller than the originals. No leaks but adjuster feel is different. The bent copper coated wire retainer clip supplied for the air valve seal was useless - no spring at all. I was able to re-use my old one, so no lost time. The fluid needle packing was a different design that the DeVilbiss original, but seems to work. The fluid needle spring was quite a bit stiffer than the original. The other seals and snap-rings were fine.
