Description
The Bedford 9-183 is a compatible replacement for Graco parts 105-445 and 105445, a ball for Graco spray equipment. This 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. Compatible with Graco 10:1 Falcon, Graco 15:1 Monark, Graco 190 Classic, Graco 190 ES (st-style), Graco 190 ES (stPro-style), Graco 190 ES Plus and other compatible equipment.
Common reasons for replacement:
- 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
- Pitting or scoring from abrasive coatings
Manufactured to OEM-equivalent dimensions for proper fit and performance.
