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
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.

Choosing Pressure Control Knob Setting

Recommendations of a starting point for determining the best set point for your sprayer and particular coating are
shown in the table below.

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.
