The GRACO 166167 is a packing nut, a critical component used to secure and seal packing material within GRACO equipment, such as pumps or valves. Its primary function is to prevent leaks by compressing the packing material around a shaft or rod. The specific material is not specified in available sources, but packing nuts are typically made from durable metals such as brass or stainless steel for longevity and corrosion resistance.

Key Features:

• Packing Nut
• 166167
• Designed for use with GRACO equipment requiring packing nuts for sealing
• Secures and compresses packing material to prevent leaks
• Designed for easy installation and maintenance
• Reliable sealing performance in demanding environments

Applications:
Used in GRACO pumps, valves, and other equipment where shaft or rod sealing is required to prevent fluid leakage.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and longevity of equipment, reducing the risk of leaks and downtime.
• Tighten the packing nut just enough to prevent leaking; overtightening can damage the packing material.
• Regularly inspect and adjust the packing nut as part of routine maintenance to maintain optimal sealing.
• Refer to the equipment manual for specific installation instructions and torque specifications.
