The GRACO 16R103 is a 13:1 ratio external mix chop system designed for fiberglass reinforced plastic (FRP) applications. It is engineered to deliver a precise mix of resin and catalyst for spray-up processes, featuring a 35 ft (10.7 m) hose for extended reach. The system is intended for use in industrial manufacturing environments where consistent, high-quality spray application is required.

Key Features:

• External Mix Chop System
• 13:1 Ratio, 35 ft (10.7 m) Hose
• Designed for use with GRACO FRP XC systems and compatible with standard GRACO components
• Optimized ratio stability for consistent spray application
• Adjustable ratio catalyst pump—no tools required for quick ratio changes
• Dual trigger function allows switching between wet-out and chop modes without removing the chopper
• Designed to minimize material waste and reduce priming solvent/resin requirements
• Engineered for durability and long service life in demanding environments

Applications:
Ideal for spray-up applications in FRP manufacturing, including boat building, automotive, construction, and industrial composite fabrication.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Follow manufacturer guidelines for hose routing and system setup
• Ensure all connections are secure and leak-free before operation
• Prime the system with minimal solvent and resin as recommended
• Regularly inspect and maintain components to prevent downtime
