The GRACO CST621 is a spray tip designed for airless spray guns, constructed from high-grade tungsten carbide for abrasion resistance. It is intended for use in airless spray systems to deliver a precise, even spray pattern for coatings and finishes, particularly in the FRP (Fiber Reinforced Plastic) and general industrial markets.

Key Features:

• Airless spray gun tip
• CST621, 0.021 in orifice, 12 in pattern width
• Tungsten carbide
• Compatible with GRACO airless spray guns and systems
• High abrasion resistance due to tungsten carbide construction
• Precision spray pattern for consistent finish
• Designed for durability and long service life
• Easy to maintain and replace

Applications:
Used for applying coatings and finishes in industrial, commercial, and FRP (fiber reinforced plastic) applications. Suitable for a variety of materials where a 12-inch fan width and fine atomization are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Ensure the spray system is depressurized before installing or replacing the tip
• Align the tip correctly with the spray gun for proper pattern orientation
• Regularly inspect the tip for wear or clogging and clean as needed
• Replace the tip if spray pattern becomes uneven or distorted
