The GRACO 108993 is a packing o-ring made from Buna-N (nitrile rubber), designed to provide a reliable seal within GRACO hydraulic reciprocator and pump assemblies. Its primary function is to prevent fluid leakage and maintain system integrity in demanding industrial environments.

Key Features:

• O-Ring (Packing)
• Buna-N (nitrile rubber)
• Compatible with select GRACO hydraulic reciprocator and pump assemblies (e.g., Dyna-Star series)
• Reliable sealing performance
• Resistant to oils and hydraulic fluids
• Designed for easy replacement and maintenance

Applications:
Used in hydraulic reciprocator and pump assemblies to seal moving parts and prevent fluid leakage. Suitable for industrial lubrication and fluid transfer applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of the equipment. Non-genuine parts may compromise system integrity and void warranties.
• Ensure the system is depressurized and isolated before installation.
• Inspect the o-ring and mating surfaces for damage or contamination.
• Lubricate the o-ring with compatible fluid before installation to prevent tearing.
• Follow the equipment manual for specific installation procedures and torque specifications.
