The GRACO 113021 Packing, U-Cup is a sealing component designed for use in GRACO displacement pumps, such as the Check-Mate 800 series. It is typically made from fluoroelastomer or similar elastomeric materials, providing reliable sealing under high pressure and temperature conditions. Its primary function is to prevent fluid leakage and maintain pump efficiency in hot-melt and other demanding industrial applications.

Key Features:

• U-Cup Packing
• Fluoroelastomer or similar elastomeric material (based on typical GRACO pump wetted parts)
• GRACO Check-Mate 800 series displacement pumps
• Designed for high-pressure and high-temperature environments
• Reliable sealing performance
• Ease of maintenance and replacement
• Durable construction for extended service life

Applications:
Used in GRACO displacement pumps for hot-melt adhesive and other high-pressure fluid handling applications in industrial settings.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment. Non-genuine parts may compromise sealing integrity and equipment reliability.
• Always follow the manufacturer’s instructions for installation and maintenance
• Inspect the packing and mating surfaces for damage before installation
• Ensure proper lubrication of the packing during installation
• Replace worn or damaged packings promptly to prevent leaks and equipment failure
