This is a piston component designed for use in GRACO equipment. It is constructed from UHMW (Ultra-High Molecular Weight Polyethylene), a durable and wear-resistant material, and is intended for heavy-duty (HD) applications. The piston functions as a critical moving part within GRACO pumps or dispensing systems, ensuring reliable operation and longevity.

Key Features:

• Piston
• 18.334 x 0.194 inches (diameter x thickness, inferred from part number)
• UHMW (Ultra-High Molecular Weight Polyethylene), Heavy Duty
• High wear resistance due to UHMW material
• Designed for heavy-duty applications
• Reliable performance in demanding environments

Applications:
Used in GRACO pumps and dispensing systems for lubrication, paint, adhesives, or other fluid transfer applications in industrial, mining, and agricultural settings.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety of the equipment. Non-genuine parts may compromise system integrity and void warranties.
• Ensure the equipment is powered off and depressurized before installation
• Clean the piston chamber and inspect for wear or damage
• Lubricate the piston as recommended by the manufacturer
• Follow all safety procedures outlined in the equipment manual
• Regularly inspect the piston for wear and replace as needed
• Use only compatible lubricants and replacement parts
• Keep a maintenance log for tracking part replacement and service intervals
