Tip Selection
Selecting Tip Hole Size
Tips come in a variety of hole sizes for spraying a
range of fluids. Your sprayer includes an 0.015 in
(0.38 mm) tip for use in most spraying applications.
Use the following table to determine the range of
recommended tip hole sizes for each fluid type. If
you need a tip other than the one supplied, see the
Reversible Tip Selection Chart on page 15.
HINTS:
As you spray, the tip wears and enlarges. Start-
ing with a tip hole size smaller than the maxi-
mum will allow you to spray within the rated
flow capacity of the sprayer.
Maximum tip hole sizes supported by the
sprayer:
– LTS 15: 0.015 in. (0.38 mm)
– LTS 17: 0.017 in. (0.43 mm)
– ProLTS 17: 0.017 in. (0.43 mm)
– ProLTS 19: 0.019 in. (0.48 mm)
Choosing the Correct Tip
Consider coating and surface to be sprayed. Make
sure you use best tip hole size for that coating and
best fan width for that surface.
Tip Hole Size
Tip hole size controls flow rate - the amount of
paint that comes out of the gun.
HINTS:
Use larger tip hole sizes with thicker coatings
and smaller tip hole sizes with thinner coatings.
Maximum tip hole sizes supported by sprayer:
– LTS 15: 0.015 in. (0.38 mm)
– LTS 17: 0.017 in. (0.43 mm)
– ProLTS 17: 0.017 in. (0.43 mm)
– ProLTS 19: 0.019 in. (0.48 mm)
Tips wear with use and need periodic replace-
ment.
Fan Width
Fan width is the size of the spray pattern, which
determines the area covered with each stroke. Nar-
rower fans deliver a thicker coat, and wider fans
deliver a thinner coat.
HINTS:
Select a fan width best suited to the surface
being sprayed.
Wider fans allow provide better coverage on
broad, open surfaces.
Narrower fans provide better control on small,
confined surfaces.
