The GRACO Seal, U-Cup (SKU:. 110284) is a piston or rod seal designed for use in GRACO displacement pumps and proportioners. The material is typically polyurethane or similar durable elastomer, engineered to provide reliable sealing in high-pressure, high-cycle fluid handling applications. Its intended use is to prevent leakage and maintain pressure integrity within GRACO equipment such as spray foam proportioners and displacement pumps.

Key Features:

• Seal, U-Cup
• Elastomeric (typically polyurethane)
• Designed for high reliability and long service life
• Easy to replace during maintenance
• Engineered for high-pressure and high-cycle applications

Applications:
Used in GRACO displacement pumps and proportioners for spray foam, lubrication, and other fluid handling systems. Suitable for industrial, agricultural, and mining applications where reliable sealing is required.

Installation Notes:

• Using genuine GRACO seals ensures optimal performance, compatibility, and longevity of the equipment. Non-genuine parts may compromise system integrity and safety.
• Inspect the seal and mating surfaces for damage before installation
• Lubricate the seal with compatible fluid to ease installation and prevent damage
• Follow the equipment manual for specific installation procedures
• Ensure proper alignment during installation to avoid premature wear
• Regularly inspect seals for wear or damage
• Replace seals at recommended intervals or when leaks are detected
• Use only compatible lubricants and cleaning agents
