  • Spray gun having indexing air cap with quick release retaining ring
    Publication number: 20030052190
    Abstract: Interlocking tabs are provided on the backside of a spray gun air cap to mate with corresponding slots in the barrel of the gun. The tabs and slots are spaced at 90° (or other spacing if desired) to confine the air cap to vertical or horizontal orientations. The barrel and retaining ring are provided with a custom coarse thread which both allows quicker removal and replacement of the air cap as well as substantially eliminating the ability to cross-thread the air cap on the barrel.
