ABSTRACT:
A paint spray gun is provided with a mounting bracket for mountably supporting the housing of the gun. The bracket has a clamping section with a substantially circular opening therein. The bracket includes a split ring for clamping the gun within the circular opening, and has a shaft extending outwardly from the clamping section for mounting in a support. The mounting bracket allows placement of plural guns in close proximity for specialty work. The gun may further be provided with a thumb operated wheel disposed in a recess in the housing for controlling the flow of fanning air, and may have the needle which controls paint flow fixedly attached to an actuator piston assembly. In a preferred embodiment, all of the seals within the gun are formed from a material which will not swell or deteriorate when the gun is immersed in an organic solvent for a period of three hours. Preferred material for the seals is polytetrafluoroethylene.
