Frequently Asked Questions

It is an OEM Graco component designed to match factory valve geometry and tolerances for compatible pumps.

Check your model’s parts manual/diagram by series and production year. Look up the intake valve assembly bill of materials and verify the seat part number is 196866.

Difficulty priming, pressure drop, pulsation, or leaks past the intake valve. Inspect the seat and mating ball/poppet for pitting or grooves.

Often yes. If the valve ball/poppet, spring, or retainers show wear, replace them together to restore seal integrity and extend service intervals.

Carbide excels with abrasive or high-solids coatings and heavy-duty use. It offers superior longevity compared to softer materials, helping maintain consistent performance.
