An assembly for providing a number of different size orifices for a sprayer unit, such as a hand-held paint sprayer, has an orifice plate with a number of orifices of different diameters radially disposed near a periphery of the plate. The plate has a centrally disposed pivot pin which is received in a complementary slot in the nozzle guard for the sprayer unit. The orifice plate has a like number of detents in the periphery thereof, and is held in place both within the slot and so as to align one of the orifices with the discharge nozzle for the sprayer unit, by a clip spring having angled free ends respectively received in detents on opposite sides of the orifice plate. Axial movement of the orifice plate is restrained by tightening the nozzle guard which is received by threads on the sprayer unit. When a different orifice size is desired, the nozzle guard is loosened, the orifice plate is rotated about the pivot pin to position the desired orifice in front of the discharge nozzle, and the nozzle guard is again tightened.
