When every painting job depends on consistent spray performance, downtime just isn’t an option. That’s why professionals using the Graco 190ES electric airless sprayer or its Hi-Boy variant insist on genuine parts—especially from trusted models like the 232903 B and 232906 B series. At Sprayersandparts.com, we provide contractor-grade OEM replacements that help you stay productive, profitable, and ahead of schedule.
Exact Bosch-grade precision:
This means perfect part fitment, pressure stability, and fluid seal reliability—no exceptions.
Tested for pressure & chemical compatibility:
OEM parts are lab-certified with a wide range of water-based and solvent coatings and designed to hold pressures up to 3,300 PSI.
Copycat parts risk seal failure, weld degradation, or catastrophic leaks.
Warranty intact, backed by expertise:
Your sprayer’s warranty stays valid when you use genuine parts.
Nothing replaces on-site experience like our in-house support from seasoned contractors and sprayer technicians.
The Graco 190ES electric sprayer, including Hi-Boy configurations, serves small- to mid-size commercial and residential painters. The two variants—232903 B and 232906 B—refer to specific paint stand and pump upgrades, but they share nearly identical components. These parts are fully cross-compatible, making inventory simpler and maintenance faster.
