Why the Graco Ultra Max II 490 Hi‑Boy Pump Stands Out

The Graco Ultra Max II 490 Hi‑Boy exists to deliver high output and reliability in heavy-duty applications—think large-scale residential exteriors, industrial jobs, and big commercial sites. Its key strengths include:

1. High Flow for Large Jobs
   With up to 0.49 gallons per minute, the Ultra Max II 490 handles everything from thick elastomeric coatings to high-build primers with ease.

2. Robust Build for Rental & Fleet Use
   Its stacked dual-drum cart and beefed-up chassis make it ideal for rental fleets and continuous operation.

3. Advanced Electronics & Pressure Control
   Integrated SmartControl™ tech helps maintain consistent finish quality, while the Hi‑Boy design keeps wear parts and electronics off the ground.

4. Versatility for Coatings & Renewable Use
   Whether spraying conventional paint, spray-grade texture, or elastomeric coatings, the Ultra Max II 490 handles it all—without sacrificing performance.

But no matter how capable the machine, it still depends on well-maintained components. That’s where high-quality OEM parts make all the difference.

Why OEM Graco Ultra Max II 490 (246428) Parts Are Non-Negotiable

Replacing parts with off-brand knock-offs is tempting—but it often compromises equipment integrity and warranties. Here’s why contractors choose OEM replacements from Sprayersandparts.com:

  Graco’s OEM parts match spec-to-spec so your maintenance won’t introduce leaks or pressure issues during high-output days.

• Rigorous Pressure & Solvent Testing
  All genuine parts are certified to handle the Ultra Max II’s operating pressures—and are chemically tested to resist degradation from coatings.

• Warranty Protection & Safety Assurance
  Insist on OEM parts to preserve your equipment’s warranty and reduce risks associated with mechanical failure.

• Expert Technical Guidance
  Our in-house technicians bring real-world experience. Whether you need torque specs or parts consulting, they’ll guide you toward the right solution.

Pro Maintenance Tips for Longevity & Uptime

1. Use a Maintenance Log
   Track operating hours and parts replacements to predict wear cycle needs.

2. Pack-OFF with Fresh Lubricant
   Always use OEM lubricant with seal kits to protect your fluid seals and maintain tight tolerances.

3. Keep Critical Spares On-Site
   Having an extra pump kit, hose section, or tip guard can prevent standstills during long jobs.

4. Clean Immediately After Use
   Leftover materials can harden inside your system—wash thoroughly after each job day.

5. Color-Code Spares Storage
   Separate parts by machine type (e.g., Ultra Max II 490 vs. Magnum LTS 17) to avoid accidental mismatches.

6. Check Tip Wear Frequently
   Old tips degrade pattern width and pressure, diminishing finish quality.

Cross-Compatibilities & Fleet-Wide Parts Strategy

Many OEM parts for the Ultra Max II 490 also fit other Graco systems—including the Magnum, TrueCoat, Ultra 395, and Fine Finish sprayers. Take advantage of parts overlap to:

• Streamline Inventory
  Keep a shared supply of high-wear items like hose kits, filters, and valves across multiple sprayer models.

• Simplify Tech Training
  Teach crews to manage one parts system, reducing errors and misorders.

• Lower Overall Cost
  Buying in bulk often reduces part costs—beneficial over the long work season.
