What is the Graco 246341 Pump Repair Kit?

The 246341 is a factory Pump Repair / Packing Kit for high-output Graco airless pumps. It replaces the fluid-section wear parts—typically upper/lower packings, O-rings, seals, and check balls/glands—restoring prime, pressure, and sealing performance without replacing the entire pump.

Frequently Asked Questions

Check your pump assembly number/series in the parts manual for your sprayer (or provide the machine serial number). Many models (e.g., GMax 7900, GH 200/230/300, HydraMax 225, LineLazer 200HS) use this kit, but some variants use different packings.

Contents vary by pump, but typically include upper/lower packings, O-rings, seals, and related check-valve components (balls/glands). It’s the standard set to rebuild the fluid section.

Basic hand tools, a clean bench, compatible lubricant for packings, and the model-specific service manual are recommended. A soft-jaw vise and torque references help ensure proper reassembly.

Yes—replacing worn packings and seals restores seal integrity, helping the pump build and hold pressure, maintain prime, and reduce pulsation for more consistent atomization.

Keep the pump clean and lubricated, use proper filtration, flush compatible solvents after use, and avoid running the pump dry. Replace worn inlet/outlet checks if you see repeated loss of prime.
