The GRACO CST221 is a spray gun tip designed for airless spray systems, featuring a 0.021 inch orifice and a 4 inch pattern width. It is constructed for use with resin and gelcoat applications, particularly in the fiberglass reinforced plastic (FRP) industry. The tip is engineered for reliable, consistent material application and is compatible with GRACO RS airless spray guns.

Key Features:

• Airless spray gun tip
• CST221, 0.021 in orifice, 4 in pattern width
• GRACO RS airless spray guns
• Engineered for resin and gelcoat applications
• Consistent spray pattern for uniform coverage
• Durable construction for extended service life
• Designed for easy replacement and maintenance

Applications:
Primarily used in the FRP (fiberglass reinforced plastic) industry for spraying resin and gelcoat materials. Suitable for both industrial and commercial applications requiring precise, uniform material application.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Ensure the spray gun is depressurized before installing or replacing the tip
• Align the tip correctly with the spray gun for proper operation
• Regularly inspect and clean the tip to prevent clogging and maintain spray quality
• Replace the tip if wear or damage is observed
• Clean the tip after each use to prevent material buildup
• Store the tip in a clean, dry environment when not in use
• Use only compatible materials and fluids as recommended by GRACO
