The GRACO 24U016 is a packing nut made from carbon steel, designed to secure and seal packing materials within GRACO pump assemblies, ensuring reliable operation and preventing leaks in high-pressure fluid handling systems.

Key Features:

• Packing Nut
• 57 mm (approximate, based on part number context; exact size may vary—check manual for precise dimensions)
• Carbon Steel
• Compatible with GRACO Dura-Flo pump lowers and similar GRACO equipment requiring packing nuts of this size and material
• Durable carbon steel construction for strength and longevity
• Designed for easy installation and maintenance
• Essential for maintaining seal integrity in high-pressure pump systems

Applications:
Used in GRACO Dura-Flo and similar pump assemblies for sealing and securing packing materials, commonly found in industrial lubrication, fluid transfer, and maintenance systems.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, seal integrity, and reliable performance, reducing the risk of leaks and equipment failure.
• Ensure the pump is depressurized and isolated before installation
• Clean the mating surfaces before installing the packing nut
• Tighten the nut evenly to avoid distortion and ensure a proper seal
• Refer to the equipment manual for torque specifications and installation procedures
• Regularly inspect the packing nut and surrounding components for wear or leaks
• Replace the packing nut if damaged or if leaks are detected
• Use only compatible fluids and solvents as specified in the equipment manual
