What It Is

The Graco 288479 Pump Piston Rod Repair Kit restores the core motion link between the drive system and the fluid section. The piston rod transfers the up-down stroke that loads and displaces coating material. This kit is commonly used when the original rod is worn, scored, bent, or leaking.

Direct fit for GH 130-series pumps (and related LineLazer 130HS configurations)
Chromex-type hard surface for improved wear and corrosion resistance
Supports proper sealing and pressure consistency after service

Frequently Asked Questions

Check the pump model stamped on your unit (e.g., GH 130) and match it in the parts manual. If your LineLazer uses a GH 130-derived pump, 288479 typically applies. For serial-range questions, consult the manual or contact support with your model & serial.

It’s strongly recommended. Packings, seals, and wipers are wear items; renewing them with the rod helps restore pressure, reduce leaks, and extend service life.

The hard-chrome/Chromex surface is designed for durability and corrosion resistance, benefiting both waterborne and solvent-borne coatings. Always follow coating manufacturer and Graco guidelines.

Use proper pressure relief, keep components clean, lubricate packings as specified, align the rod carefully to avoid scoring, and tighten to the correct torque. Replace any damaged seats/balls at the same time.

Persistent packing leaks, visible rod scoring, irregular pressure, or bent/runout conditions. If these appear, replacing with 288479 can restore performance.
