The GRACO 166178 PACKING O-RING is a sealing component designed to prevent leaks and maintain pressure integrity within GRACO spray equipment. It is typically made from rubber or a similar elastomeric material, engineered for durability and resistance to wear from paints, coatings, and solvents. Its primary function is to seal moving parts in the pump assembly, ensuring reliable operation and minimizing maintenance downtime.

Key Features:

• Packing O-Ring
• Rubber or elastomeric material
• Designed for use with GRACO spray equipment; specific model compatibility should be confirmed with the equipment manual
• High durability and wear resistance
• Engineered for reliable sealing in harsh environments
• Ease of maintenance and replacement

Applications:
Used in GRACO spray equipment to seal pump components, preventing leaks and maintaining system pressure during operation. Suitable for use in paint, coating, and spray foam applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of the equipment. Non-genuine parts may compromise seal integrity and equipment reliability.
