Key Parts for the Graco 495 Sprayer

 Piston Pump & Valves

At the heart of any airless sprayer, the piston pump pressurizes paint for atomization. Regular maintenance—such as repacking pistons and inspecting inlet/outlet valves—is essential. Worn valves often cause leaks, poor pressure control, or inconsistent flow.

 Filters & Strainers

Debris-free operation begins with clean filters and strainers. The 60-mesh Easy‑Out filter (part 246384) is designed to catch contaminants before they clog your spray tips or damage pump components.

 Fluid Manifold & Sewings

This critical junction distributes fluid across internal passages. It requires periodic inspection—especially O-rings and seals prone to wear and tear. Replacement kits ensure safe, leak-free function.

 Pressure Transducer & Control Dial

Precision control over paint flow ensures optimal finish. The transducer regulates pressure and is included in Graco’s rebuild kits. Replacing worn pressure control parts restores also accuracy.

 Hoses, Couplers & Gun

High-pressure hoses—typically 50‑foot DuraFlex units—and couplers connect the pump to the gun. A whip hose increases maneuverability. Hose fittings and a quality spray gun complete the setup.

Maintenance: Best Practices & Tips

• Regular cleaning: Run solvent through the system after use and before storage to prevent clogging and corrosion.
• Repacking pump annually: A worn piston seal—often overlooked—can decrease spraying power.
• Store hoses dry: Water can lead to rust in end fittings; flush with thinner or Pump Armor before storage.
• Keep spare filters & O-rings: Having extra parts on-site minimizes interruptions during jobs.

“I have a Graco 495 that is over 20 years old because I’ve been able to repack the piston multiple times… invest in something that you can have long term.”

Choosing the Right Configuration

Graco offers various 495 variants:

• 495 ST ProB (220–240 VAC): Stable, high-capacity sprayer
• Ultra 495 XT Electric: Compact, electric-powered convenience
• Ultra Max II 495 PC: Peak performance variant for heavy-duty tasks

Troubleshooting Common Issues

• Pulsing spray stream: Often due to a stiff or short hose. Use the standard 50‑foot with proper diameter to smooth output.
• Pressure drops mid-job: Check filters and valves—clean or replace if needed.
• Rust in hoses: Likely from water retention. Proper cleaning prevents rusting.
