  • Prevent incorrect orders and downtime with expert product advice

Pro Tips for Long-Term Reliability

  • Track service intervals: Replace wear parts like seals, pistons, and guides proactively.
  • Use fresh lubricant: Every seal kit install should include lubricant to extend pack-off life.
  • Stock spares: Keep a ProXChange cartridge (24Y472) on hand for emergency swaps.
  • Clean your strainers: Use color-coded inlet strainers like part 245673 to prevent clogging.
  • Organize parts bins: Color-code or label small parts to avoid jobsite confusion.

Why It Matters for Contractors

Genuine Graco parts help you:

  • Reduce downtime with quick-swappable OEM parts
  • Maintain consistent spray patterns for fewer touch-ups
  • Protect resale value by keeping sprayers in top shape
“Replacing valves and seals often solves pressure or spray issues without needing a full pump swap.”
