- Ultra 495 paint sprayer—identical gland nut and piston dimensions mean the same graco 495 paint sprayer kit rebuilds both.

10,000-Hour Maintenance Roadmap
- Daily: Flush with FastFlush for 45 s, add three drops of TSL on the plunger.
- Every 500 gal: Replace 60-mesh manifold filter; inspect inlet strainer.
- Every 1,000 h: Install a new 246428 pump lower one pin, one jam nut log the swap on your graco pump parts diagram for warranty traceability.

Pro Tips to Maximize Uptime
Color-code parts drawers. Keep graco sprayers parts for 390-595 in blue bins, 7900 graco paint sprayer consumables in red, and graco spray gun parts in yellow for lightning-fast grabs.
Carry a mini torque wrench. Over-tightening the gland nut by just 10 ft-lb can distort the Chromex rod seat and halve packing life.
Use BlueLink hours. Set alerts at 900 h so crews plan a swap, not react to a failure.
