Airless spray gun tips are interchangeable tips for airless spray guns that break up paint into an even, fine mist when it leaves the gun. They can be used to spray different materials. Use smaller opening sizes when painting with lighter or thinner liquids, such as stains and lacquers, and larger opening sizes for heavier and thicker liquids, such as latex paint. Airless spray tips allow a worker to select how much fluid will leave the gun when they spray paint, as well as how wide the fan of the spray will be. Airless spray gun twist tips can be twisted to widen or narrow a gun's tip orifice size.
