Description
The Bedford 17-3835 is a compatible replacement for Graco parts 162947 and 162-947 — the ball stop pin used in 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 President, 5:1 Monark, and Viscount I 1000.
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.
