What Is the Graco 287813 Pump Packing Repair Kit?
The 287813 is a factory packing/repair kit for the fluid section of compatible GH-series pumps. It replaces the internal wear and sealing components (e.g., packings, O-rings, glands, and check components) to restore pressure, reduce leaks, and extend pump life—without replacing the entire pump.

Frequently Asked Questions
It fits common GH 200, GH 230, and GH 300 configurations. Always verify the exact model/series from your pump’s parts list to ensure you order the correct kit for your unit.
Falling pressure, material bypass around the rod, leakage at the throat, excessive pulsation, or poor spray pattern typically indicate worn packings that should be replaced.
Basic hand tools are usually sufficient. Follow the service manual for disassembly, packing stack order, lubrication, and torque values. A clean bench and proper rod support help avoid damage during reassembly.
No. The kit replaces sealing components. If the rod or cylinder is scored or out of tolerance, repair or replacement of those parts is required for a lasting fix.
Intervals depend on material type, filtration, and run hours. Many contractors repack on a preventive schedule (e.g., after heavy projects) or at the first signs of leakage/pressure loss. Consult your machine’s manual for guidance.
