Frequently Asked Questions
Check the model decal for GMax II 7900 IronMan and the frame style (Hi-Boy, Lo-Boy, or Roof Rig). If it matches the models listed above, this cylinder is the correct OEM replacement. When in doubt, provide your full model & serial number to confirm compatibility.
It’s strongly recommended to replace packings/seals while the pump is open. Fresh sealing components help restore pressure, reduce leakage, and extend the life of the new cylinder.
Hi-Boy sprayers have taller carts with higher hose & gun storage and usually larger wheels for jobsite maneuverability. Lo-Boy frames sit lower for easier loading and transport. The pump cylinder compatibility is determined by the sprayer’s specific 7900 IronMan configuration noted above.
Installation Tips
- Clean the fluid section thoroughly; avoid scoring the new cylinder during assembly.
- Lubricate packings per Graco guidelines before reassembly.
- After installation, prime with clean solvent or water (per coating) and check for leaks at low pressure before full operation.
