Select a Fluid Nozzle and Air Cap

The gun is supplied with Part No. 197266 Nozzle and 24A276 Air Cap. If you require a different size, refer to Table 1 and Table 2 , and instruction manual 309419, or consult with your Graco distributor. See Replace Air Cap/Nozzle on page 28.

A wide pattern kit (P/N 24A431) is included with the gun and if installed, will provide more fan air for wider spray patterns. (If pattern becomes split, use the fan air valve to reduce the amount of fan air.)

To reduce the risk of an injury, follow the Pressure Relief procedure on page 19 before removing or installing a fluid nozzle and/or air cap.

NOTE: Due to the larger needle diameter, use a nozzle one size larger than you would use with a standard Pro Xs gun (i.e., 1.5 mm = 1.2 mm flow area).
