Combining the correct spray tip with your spray gun plays a big role in helping you create the professional finish your spray job requires. Not only does the tip determine how much fluid will leave the gun when you pull the trigger, the spray tip also determines how wide a spray fan the gun will create.

Choose a paint spray tip with an orifice size rated for the paint or coating you’ll be spraying. Light coatings such as lacquers, stains, and enamels require a small tip, while heavier coatings such as texture require larger spray tips. Many paint manufacturers will specify recommended spray tip sizes on the container or product specification sheet so it is always good to confirm with the manufacturer of the coatings.

Recommended Tip Sizes For Common Coating Materials

Many OEM's identify their paint spray tips by a three-digit code. The first number, when multiplied by 2, tells you how wide of a fan the tip will create when sprayed at a distance of 12 inches from the surface. The second two numbers are the orifice size of the tip, in thousandths of an inch, that determines how much fluid will leave the spray tip. For example, a 513 tip will spray a 10-inch-wide fan and have a 13-thousandths of an inch orifice. It’s the combination of fan-width and orifice-size that determines how thick of a coating you’ll spray.
