What is the Graco 287816 Pump Rod?

The Graco 287816 Pump Rod (also referred to as a piston rod) is a critical internal component of the fluid section that converts drive motion into reciprocating piston movement. Replacing a worn rod restores sealing surface integrity and helps maintain prime, pressure, and spray consistency on compatible GH-series machines.

Installation Tips

Depressurize and follow lock-out/tag-out procedures before servicing.

Frequently Asked Questions

Check your sprayer’s model, series, and serial range against the GH-series parts manual. If your unit is a GH 230 or GH 300 in the listed series ranges, the 287816 Pump Rod is the correct rod. When in doubt, match by exploded-view diagram and rod reference number in your manual.

Yes—rod wear often coincides with packing wear. Replacing the rod and installing a fresh packing kit helps restore sealing and extends service life. Inspect the fluid cylinder for scoring before reassembly.

No. The 287816 Pump Rod is listed for GH 230 and GH 300 gas-hydraulic rigs. Electric units (e.g., Ultra/Ultra Max II) use different fluid-section components and rod part numbers.

Follow the GH-series service manual for safe disassembly and reassembly. Use appropriate wrenches, soft-jaw vise protection for polished parts, thread treatments where specified, and the manufacturer-specified torque values for connecting hardware.

Listings may vary. Typically you’re purchasing the pump/piston rod itself. If a full repair kit is needed (packings, seals, etc.), add the matching GH-series packing kit and any other wear parts shown for your model in the parts breakdown.
