Frequently Asked Questions

The 109303 Vee Packing forms a reliable seal on the piston or throat of Graco displacement pumps, preventing fluid from bypassing the packing gland and maintaining pump efficiency.

This component is designed specifically for use in Graco pump assemblies. Using it in other brands may lead to improper fit or reduced sealing performance unless confirmed by the manufacturer.

Ensure the piston/rod and gland areas are clean and undamaged before installation. Follow the Graco manual for correct orientation, preload of the packing stack, and ensure the installation of the lips of the packing conform to the original assembly instructions.

PTFE offers excellent chemical resistance, a low coefficient of friction, and strong durability under high pressure—making it an ideal material for dynamic seals in industrial pump applications.
