Choosing the Correct Tip
Understanding Tip Number
The last three digits of tip number (i.e.: XXX517) 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.
Example:
For a 10-12 in. (254-305 mm) fan width and a
0.017 in (0.43 mm) hole size, order part number
PST517, 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 0.017 in.
(0.43 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.
