Frequently Asked Questions

Compatibility for 102769 depends on the exact model and configuration. Check your unit’s illustrated parts list or contact support with your model/serial to confirm the correct O-ring or packing kit.

Many repairs are best done with a complete OEM packing kit to replace all wear components together. Check your manual; if the parts list calls out a kit, use that kit number for the most reliable service outcome.

Loss of pressure, difficulty priming, leakage at the pump, and inconsistent spray patterns typically indicate packing wear or O-ring damage and signal the need for service.

Use calipers to measure the O-ring groove and cross-section, then match those specs to the official parts book. When in doubt, provide your exact sprayer model to confirm the correct part number.

Yes—102769 is a genuine Graco replacement Packing O-Ring. Always verify by part number before ordering.
