Description
The Bedford 9-3189 is a compatible replacement for Graco parts 118-601 and 118601 — the ceramic ball used in Graco spray equipment. This ceramic ball is the moving element of a check valve in the pump’s fluid section: on each stroke it lifts off its seat to let coating through, then reseats to hold pressure. Ceramic shrugs off corrosion and abrasion, which makes it a common upgrade path for waterborne and aggressive materials. Compatible with Graco DutyMax, GMax II 7900, GMAX II 7900 (2014+), GMax II 7900 HD, Mark V SpackMax, Mark X and other Graco equipment.
Common reasons for replacement:
- Pitting or scoring from abrasive coatings
- Replaced together with its seat during a fluid-section rebuild
- Sprayer loses prime or pressure as the ball wears out-of-round
- Fluid backflow from a ball that no longer seats cleanly
Manufactured to OEM-equivalent dimensions for proper fit and performance.
