• 0.312 inches diameter
• Aluminum oxide ceramic (Al₂O₃)
• GRACO Xtreme lower pumps (36–58 cc piston)
• High durability and wear resistance
• Reliable sealing and valve function
• Long service life in demanding industrial environments

Applications:
Used in GRACO Xtreme lower pumps for industrial spray equipment, particularly for handling abrasive or corrosive fluids in coating and lubrication systems.

Installation Notes:

• Using genuine GRACO ceramic balls ensures optimal performance, reliability, and longevity of the pump assembly. Non-genuine parts may compromise equipment function and safety.
• Ensure the pump is depressurized and cleaned before replacing the ceramic ball.
