Badger Air-Brush Company Stock Number 20-107 Sotar Paint Tip, Medium (size 2) is a stainless steel self centering compression fit component that sits in the nozzle head and is held in place by the hold down ring. The opening size for this tip is .40 millimeter, creating a spray pattern of a pencil line up to one-inch (25 millimeter). The tip is a necessary component needed to properly guide the media/paint over the needle before releasing it from the airbrush. Pulling back on the trigger retracts the needle into the airbrush allowing more or less paint to flow through the tip of the airbrush. Badger Air-Brush parts are proudly made in America.
