Graco Flat Spray Tips

Tip Model: 163
This is a general guideline to help you select a tip. BlastOne as a Graco distributor can recommend a tip based on experience with any application project, or assist in the conduction of test to find the best product.

Orifice Size and Spray Width

Orifice size determines how many gallons per minute can be atomized through the airless spray tip. The last two digits of the part number tell the orifice size in thousandths of an inch.

For Example: The orifice is .015” (0.381 mm) with tip number 163-415.

Spray width is based on spraying 12 inch (305 mm) from the surface. Double the fourth digit of the tip part number to determine the approximate minimum spray width in inches. Add two inches to that number for maximum width.

For Example: This tip size produces a 8–10” (203 – 254 mm) spray pattern at 12” (305 mm) from the surface.
