Frequently Asked Questions

Check the pump/packing section of your official Graco parts manual for your exact model. If it lists Pump Packing Repair Kit 287825, this is the correct kit. If not, use the listed part number instead.

Common signs are loss of pressure, inconsistent spray pattern, material bypass/leakage, or frequent priming issues. Visible wear on the rod or packings also indicates service is due.

Standard mechanic’s tools typically suffice. Follow the Graco service procedure for the Mark IV pump. A soft-jaw vise, torque wrench, and packing tools can speed up the job and help avoid damage.

Inspect the piston/rod, cylinder, and check valves/balls & seats. If any are pitted or worn, replace them to prevent premature packing wear. Always flush and test after reassembly.

This kit is specified for Mark IV pump assemblies that list 287825 in the manual. Other TexSpray models often use different packing kits. Always confirm by part number in your unit’s documentation.
