Aftermarket GRACO® 100279 Piston Ball, Steel (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 300837

Comparable OEM Part Number: 100279

Description: Total Finishing's part # 9-127 is a compatible replacement for GRACO® parts 100-279 and 100279 — the ball 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® 1:1 Fast-Ball, 1.5:1 Monark, 10:1 President, 13:1 Senator Dura-Flo 1200, 2:1 Monark, 2:1 Standard and other GRACO® equipment.

Common reasons for replacement:

• Fluid backflow from a ball that no longer seats cleanly
• 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

Manufactured to OEM-equivalent dimensions for proper fit and performance.
