✅ Tested for chemical compatibility and pressure ratings
Genuine Graco components undergo rigorous testing to ensure they can handle the demanding coatings, pressures, and chemicals used in today’s toughest jobs. Copycat parts rarely meet these standards — risking failure and costly delays.

Having essentials like Graco paint sprayer attachments on hand helps you avoid work stoppages during multi-day or remote site jobs.
