Pro Tips for Long‑Term Reliability

Your Graco 455 ST Pro Gun airless paint sprayer is designed for years of dependable use — but like any professional tool, it requires proper care. Follow these pro tips to extend service life and minimize unplanned downtime:

Document service intervals
Track when seals, filters, and other wear parts were last replaced. Preventative maintenance is cheaper (and faster) than emergency repairs.

Always pair new seal kits with fresh lubricant
Lubricating packings and seals when installing extends their lifespan and keeps your gun operating smoothly.

Stock spare parts to minimize delays
Having extras like Graco paint gun accessories or Graco machine parts on hand means you can handle issues without waiting for shipping.

Organize with color-coded bins
Keep your shop or truck organized. Separate similar parts — like those for your Graco 230 paint sprayer or Graco 395 paint sprayer — to prevent mix-ups and wasted time.

These simple steps will help you protect your investment and keep your projects moving forward.
