Choosing the Correct Tip

Understanding Tip Number

The last three digits of tip number (i.e.: XXX413) con- tains information about hole size and fan width on sur- face when gun is held 12 in. (30.5 cm) from surface being sprayed.

First digit when doubled = approximate fan width

413 tip has

8 - 10 in. fan width

413 tip has

ti19498a

a 0.013 in. hole size

Last two digits = tip hole size in thousands of an inch

Example: For a 6 - 8 in. (152 - 203 mm) fan width and a 0.015 in (0.38 mm) hole size, order part number PST315 or NAR315, depending on your sprayer model number.

Selecting Tip Hole Size

Tips come in a variety of hole sizes for spraying a range of fluids. The sprayer includes a 0.015 in. (0.38 mm) tip for use in most spraying applications. Use the table below to determine the range of rec- ommended tip hole sizes for each fluid type.

Consider coating and surface to be sprayed. Make sure to use the best tip hole size for the coating and best fan width for that surface.

Tip hole size controls flow rate - the amount of paint that comes out of the gun.

HINTS:

As you spray, the tip wears and enlarges. Starting with a tip hole size smaller than the maximum will allow you to spray within the rated flow capacity of the sprayer.

Tips wear with use and abrasive paint and need periodic replacement.

Do not spray with worn spray tips. Poor spray pattern quality will result.
