As mentioned, we need to also do the fan width calculation.Īs an example, take a 315 and a 515 spray tip. When comparing the 3 digit codes of spray tips we can decide which Graco Paint Sprayer tips will create the thicker or thinner coat. For example, a 315 tip means that the spray angle is 30 degrees and the orifice is 0.015 inches big. The final two numbers are the orifice size in thousands of an inch, just as explained in the previous section. This gives you the fan width when spraying at a distance of 12 inches from the surface. To find the fan width size in inches, multiply the first number by 2. The number goes from 1 – 5 with 1 being the most narrow and 5 being the widest angle. Adding a 0 to the first number gives you the spray angle.įor example, a 2 at the front means a narrow 20 degrees angle and a 5 at the front means a wider 50 degrees angle.
The first number in the 3 digit sequence refers to the paint spray angle from which the fan width can be calculated. The numbers refer to a different aspect of the tip so it is much more detailed than the guesswork based on paint material thickness.

Airless Paint Sprayer 3-Digit Code ExplainedĪirless paint sprayer tips are categorized with a 3 digit code which is highly informative.
This is a very basic approach but might still be good enough for beginner tools and those that are new to DIY tasks. Thicker and more viscous materials such as latex paint, fillers and paint jobs with texture require larger tip sizes and can be greater than 0.035 inches. Thinner layers and less viscous materials such as stains, enamels, and lacquers are compatible with smaller size tips generally 0.009 – 0.015 inches.
