The GRACO 166730 is a Vee packing, typically made from rubber, designed to provide a reliable seal within GRACO pump assemblies. It is used as a replacement or upgrade part to convert certain GRACO pumps to rubber-packed configurations, replacing leather and PTFE packings for improved sealing performance and durability.

Key Features:

• Vee packing
• 166730
• Rubber (material inferred from application notes)
• Compatible with specific GRACO pump models (e.g., for converting to rubber-packed pumps, replacing 8 leather and 2 PTFE packings)
• Provides reliable sealing in pump assemblies
• Used for converting pump packing material
• Designed for ease of replacement and maintenance
• Lubrication recommended during installation

Applications:
Used in GRACO pump assemblies to ensure proper sealing and prevent leaks, especially in high-pressure fluid handling systems. Suitable for converting certain GRACO pumps to rubber-packed configurations for enhanced performance and longevity.

Installation Notes:

• Using genuine GRACO packings ensures optimal fit, performance, and longevity of the pump assembly.
• Lubricate all Vee packings before installation
• Ensure correct orientation of Vee packing lips (direction depends on installation location—throat or piston gland)
• Follow manufacturer torque specifications for gland/packing stack assembly
• Remove shims when installing in pump throat; leave shims in place when installing on piston to ensure correct stack height
• Regularly inspect packings for wear and replace as needed
• Use only recommended lubricants and genuine parts
• Follow GRACO service guidelines for pump maintenance
