Graco Ultra Max II 495 Stand Pump (246428) Breakdown: Key Components

The Graco 495 Stand Pump (246428) is the heart of the Ultra Max II sprayer system. It’s built for mid-volume commercial work, making it essential to keep every component in peak condition.

Here’s a breakdown of the core parts available for fast reorder or preventive maintenance:

 Pump Cylinder & Piston Rod

At the center of your sprayer's power stroke, the piston rod and pump cylinder must be free of pitting and wear. Use our complete cylinder kits for quick rebuilds that restore flow and pressure.

 Upper & Lower Packings

These internal seals keep fluid from escaping during the pump cycle. Our OEM packing kits are pre-lubed and built for long life—even in high PSI applications.

 Inlet Valve & Outlet Valve Assemblies

Key for maintaining a closed fluid system and preventing cavitation. If your sprayer is pulsing or sputtering, inspect and replace with our matched valve kits.

 Pump Repair & Rebuild Kits

We carry complete rebuild kits that include all necessary packings, seals, washers, and springs. Ideal for shops that want to restore performance without buying a whole new pump assembly.

 Graco Spray Tip Guards & Filter Elements

Match your tips to your application and your guards to your gun for safe, efficient spraying. Our tip guards are compatible with both the Ultra Max II 495 and Graco Magnum X7 for multi-tool consistency.

Pro Tips for Long-Term Sprayer Reliability

You don’t have to wait for a breakdown to start thinking about maintenance. Keep your Graco Ultra Max II 495 Stand Pump running like new with these field-tested strategies:

Log Service Intervals

Use a physical job folder or digital app to track when your packings, filters, and pistons were last replaced. Staying ahead of wear prevents complete system failures on high-value jobs.

 Lubricate New Seals Immediately

Every new Graco seal kit should be installed with OEM-approved grease. This extends the compression life and prevents premature swelling or cracking from harsh solvents.

 Keep Backup Units Handy

Especially for contractors on multi-day or remote projects, consider stocking a spare Graco X7 or LTS 17 with essential parts on-hand to eliminate jobsite downtime.

 Use Color‑Coded Storage Bins

Keep parts organized by size, type, and usage. Use one bin for Graco texture guns, another for line striping parts like those from the Graco FieldLazer S100, and another for airless spray gun rebuild kits.

Smart Tools for Smarter Repairs

Make informed repair decisions with our Contractor Knowledge Hub. Whether you're new to airless sprayers or a seasoned shop lead, you'll find resources that save time and money:

 Pressure Drop Calculators

Optimize your tip and hose setup based on material type and jobsite distance.

 Chemical Compatibility Charts

Find the best seal materials for your specific coatings—whether you're spraying elastomeric roof coatings, epoxy floor systems, or interior latex.

 Superseded Part Cross‑Referencing

Avoid delays from discontinued SKUs by checking our updated listings with alternative part numbers and recommended replacements.
