Badger Air-Brush Co Stock Number 50-0393 Heavy Tip for Model 100, 150 and 200 airbrushes. The tip of the airbrush sets in the head of the airbrush. The nickel silver alloy tip properly guides the paint over the needle before releasing it. The tip is sealed with beeswax to insure an airtight bond. As the needle retracts through the tip, it increases the release of paint. The size of the tip (fine, medium, heavy) must be compatible with the airbrush spray regulator and needle for airbrushing accuracy. Precision manufactured utilizing a durable metal alloy. Badger Air-Brush parts are proudly made in America.
