The GRACO 166119 is a packing or O-ring designed for use in GRACO positive displacement pumps and related equipment. It is typically made from Buna-N (nitrile rubber), a material known for its resistance to oils, fuels, and chemicals, making it suitable for sealing applications in demanding environments. This part is intended to provide a reliable seal within pump assemblies, preventing leaks and ensuring efficient operation.

Key Features:

• Packing, O-Ring
• Buna-N (nitrile rubber)
• Compatible with GRACO positive displacement pumps, including SaniForce series
• Reliable sealing performance
• Resistant to oils, fuels, and chemicals
• Easy to replace during maintenance

Applications:
Used in GRACO positive displacement pumps for sealing critical components, ensuring leak-free operation in industrial, agricultural, and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal fit, performance, and longevity of the equipment. Aftermarket alternatives (e.g., Bedford 0-984) are available but may vary in quality and compatibility.
• Inspect the O-ring for damage or wear before installation
• Ensure the mating surfaces are clean and free of debris
• Lubricate the O-ring with compatible grease if recommended by the manufacturer
