Description

Graco 249001 – Pump Piston Rod (OEM)

Compatible Machines

The Graco 249001 Pump Piston Rod is used in the following gas-hydraulic Graco sprayer families (verify generation/serial in your parts manual):

Graco GH230 – 2nd & 3rd Series (e.g., Standard/ProContractor, including models such as 24W929, 24W930)

Product Overview

The Graco 249001 Pump Piston Rod is a precision-ground drive component that links the drive system to the fluid section piston in high-pressure, airless applications. A straight, hardened rod preserves seal life, maintains alignment, and sustains consistent pressure output in demanding duty cycles.

Key Benefits

OEM fit & finish for correct alignment and long packing life.
High-strength construction to withstand continuous high-pressure cycling.
Restores spray performance when a worn or scored rod causes pressure loss or leaks.

Installation & Care

Inspect old rod for scoring before re-packing; replace if damaged.

Frequently Asked Questions

Check your sprayer’s series (2nd/3rd), the pump assembly installed (e.g., 24W997, 248736), and your exact model/serial in the Graco parts manual or IPB. If your sprayer is within the GH230 or GH300 families listed above and uses those pump modules, 249001 is the correct rod.

Loss of pressure, uneven stroke, frequent packing failures, leakage at the fluid section, or visible scoring/corrosion on the rod surface are common indicators.

This listing is for the OEM Pump Piston Rod (249001). Some assemblies or aftermarket kits may include additional hardware; refer to the item’s components list or your parts manual if you require a rod-and-pin kit.

249001 is the piston rod itself. Assemblies like 24W997 are complete pump modules (fluid sections) that contain multiple parts—including a rod—specified for the sprayer family/series.

Keep the rod and packings clean and lubricated, follow torque specs and alignment steps from the manual, and replace worn seals/packings together with the rod if scoring is present. Always pressure-test before returning to service.
