The GRACO 184112 NUT, PACKING is a replacement part designed for use in GRACO pumps and fluid handling equipment. It is typically constructed from durable metal and is intended to secure and seal the packing material around the pump shaft, preventing leaks and ensuring reliable operation. Its primary function is to maintain proper compression on the packing, which is essential for the longevity and efficiency of the pump.

Key Features:

• Packing Nut
• Designed for use with compatible GRACO pump models (specific models not listed for 184112)
• Secures and compresses packing material
• Helps prevent leaks at the pump shaft
• Designed for easy maintenance and replacement
• Contributes to pump reliability and longevity

Applications:
Used in GRACO pumps and fluid handling systems for sealing the pump shaft and preventing fluid leaks. Suitable for industrial, mining, and agricultural applications where reliable pump operation is required.

Installation Notes:

• Using genuine GRACO packing nuts ensures proper fit, seal, and performance, reducing the risk of leaks and equipment failure.
• Adjust the packing nut weekly so it is just snug; do not over-tighten.
• Follow the pressure relief procedure before adjusting the packing nut.
• Torque the packing nut to the manufacturer’s recommended specification (for similar GRACO models, typically 27–34 N.m / 20–25 ft–lb, but confirm for your specific model).
• Fill the packing nut/wet-cup 1/3 full of GRACO Throat Seal Liquid or compatible solvent as recommended.
• Reconnect all hoses and ground wires after installation.
• Run the pump slowly after installation to check for leaks and proper operation.
• Regularly inspect and adjust the packing nut to maintain proper compression.
• Use only recommended lubricants or sealants.
• Replace the packing nut if it shows signs of wear or damage.
