Tip Sizing & Gun Filters

Choosing the correct tips and filters can be a little confusing, due to a wide range of nozzle shapes and sizes. The tip is selected depending on the viscosity of the paint and width of fan pattern required. We hope the guide below will aid your tip selection but, as always, please feel free to telephone for verbal advice.

The average distance from the tip to the object is about 6 to 10 inches (15–25 cm). When spraying and moving back and forth over the surface, each stroke should be overlapping the previous to ensure a continuous coat.

Atomization is created be by the material being forced to go through the small hole (Orifice) of the tip under high pressure. This process atomises the paint in a controlled fan width and flow rate.

Tip Angle & Orifice Diameter





The first digit on the tip indicates the nozzle angle. It is also used as a guide to determine the fan width, simply double the number

2 = 20° 4 Inches

3 = 30° 6 Inches

4 = 40° 8 Inches

5 = 50° 10 Inches

6 = 60° 12 Inches

The second two digits indicate the orifice diameter. This helps regulate material flow which determines the amount of paint applied.


13 = 0.013″ (13 thou)

15 = 0.015″ (15 thou)

17 = 0.017″ (17 thou)

19 = 0.019″ (19 thou)
