The GRACO 15F748 is a U-cup piston seal designed for use in GRACO fluid handling equipment. It is typically made from durable elastomeric materials suitable for sealing pistons in high-pressure and high-cycle applications. Its primary function is to prevent fluid leakage and maintain pressure integrity within the piston assembly.

Key Features:

• U-Cup Seal
• E10
• Designed for reliable sealing in piston assemblies
• Suitable for high-cycle and high-pressure environments
• Compact and lightweight for easy installation and maintenance

Applications:
Used in GRACO fluid handling and spray equipment where piston sealing is required, such as in paint sprayers, lubrication systems, and other industrial fluid delivery systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and compatibility with GRACO equipment.
• Ensure the piston and seal surfaces are clean and free of debris before installation
• Lubricate the seal as recommended by the equipment manual
• Inspect the seal for damage or wear before installation
• Follow manufacturer guidelines for installation torque and alignment
• Regularly inspect seals for wear or damage
• Replace seals at recommended intervals or when leaks are detected
• Use only compatible lubricants and cleaning agents
