The Art Primo Airbrush Cap offers precise, super-fine lines and excellent control for detail work as well as a special clog resistant nozzle. This cap surpasses all of our other super skinny caps in line size - with Flame Blue expect a clean pinky sized line or smaller. Features a higher pressure output than our Grey/Gold Dots. This cap was designed for the Flame Blue spray paint line but works with most European low pressure paint. Green Ranger approved!
