Overview of the Graco 69421ST Uni-Tip 421 S Tip Assembly

The Graco 69421ST Uni-Tip 421 S Tip Assembly is a genuine spray tip used in airless paint spraying systems. It controls how coating material exits the spray gun, determining both the spray fan width and the amount of fluid delivered during application.

The 421 tip size indicates a spray fan pattern of approximately 8–10 inches and a 0.021-inch orifice. This configuration is well suited for medium to heavier coatings such as primers, latex paints, and protective coatings used in residential, commercial, and industrial spraying tasks.
