Why OEM Matters: The Value of Genuine Graco 490 XT Parts

1. Precision Engineering for Consistent Fit & Output

OEM components are crafted within exact tolerances. That means you’ll maintain steady pressure, a stable spray pattern, and reliable performance—every time.

Graco tests each part under rigorous conditions: high-viscosity coatings, solvents, high temperatures, and extreme pressures. Counterfeit or aftermarket parts frequently fail these criteria—leading to costly downtime.
