Pro Tips for Maximum Equipment Lifespan

To get the most out of your Graco sprayer, proper maintenance and proactive part replacement are essential. Below are a few proven strategies our professionals recommend:

1. Schedule Preventive Maintenance
Document routine service intervals and replace wear items before performance declines. A simple schedule can prevent major system failures during critical job phases.

2. Always Use Fresh Lubricant with Seal Kits
When installing a new seal kit, apply fresh, compatible lubricant to extend the life of pack-off systems and maintain pressure efficiency.

3. Keep a Spare Spray Gun Handy
Having an extra Graco Magnum X7 replacement spray gun or similar model ready can save hours or even days of lost productivity if the primary gun fails mid-job.

4. Organize Parts by Type
Use color-coded bins or labeled containers to separate frequently used parts such as Graco texture sprayer guns and Graco airless paint sprayer accessories. This allows quick access and reduces mix-ups during high-pressure situations.

Beyond parts, we provide valuable resources designed to help you make informed purchases and upgrades:
