The GRACO 183039 Packing Piston is a replacement part designed for use in GRACO pumps and spray equipment. It is typically made from polyethylene, providing durability and resistance to wear. Its primary function is to maintain a tight seal within the pump assembly, preventing fluid leakage and ensuring efficient operation of the equipment.

Key Features:

• Packing Piston
• Polyethylene
• Designed for GRACO pumps and spray equipment; specific compatibility should be verified with equipment manual or GRACO specialist
• Durable polyethylene construction for long service life
• Designed for easy replacement and maintenance
• Helps maintain pump efficiency by preventing leaks

Applications:
Used in GRACO pumps and spray equipment for sealing and maintaining pump integrity in various industrial, agricultural, and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of equipment. Non-genuine parts may compromise pump efficiency and safety.
• Always refer to the equipment manual for specific installation instructions
• Ensure the pump is depressurized and cleaned before replacing the packing piston
• Inspect related components (such as seals and O-rings) for wear and replace if necessary
• Tighten packing nuts to recommended torque specifications (for reference, GRACO manuals often specify 34–40 N·m or 25–30 ft-lb for similar components)
