Why Choose Genuine Graco 390 Electric Airless Lo-Boy Sprayer Parts (24U106)?
Not all sprayer parts are created equal. Here’s why OEM parts from Sprayersandparts.com deliver better results and peace of mind:

Smart Pro Tips to Extend the Life of Your Graco 390 Lo-Boy Sprayer
1. Follow a Service Schedule
Track your rig’s runtime and replace filters, tips, and packings at regular intervals. Ignoring service leads to performance loss and expensive rebuilds.
2. Always Replace Seals with Fresh Lubricant
A worn pump kit combined with dry packings is a recipe for failure. Use Graco-approved TSL (Throat Seal Liquid) or pump armor with every seal replacement.
3. Keep Critical Spares in Stock
Store backup graco spray tips, filters, pressure valves, and power switches so you’re never waiting on parts during active jobs. Multi-day projects rely on your uptime.
4. Use Organized Storage
Color-code bins for different sprayers or rig types especially when storing small parts for Graco 7900 units or drywall texture sprayer components. This reduces errors during field repairs.
