The GRACO 100279 is a metallic ball component, typically made from stainless steel and zinc plated for corrosion resistance. It functions as a check ball within GRACO pumps, such as the 10:1 Fire-Ball 425 Pump, ensuring proper fluid flow and preventing backflow in high-pressure fluid handling systems.

Key Features:

• Check ball
• Height: 0.85 inch, Length: 0.8 inch
• Stainless steel, zinc plated
• GRACO 10:1 Fire-Ball 425 Pump and compatible systems
• Exceeds 72-hour salt spray test for corrosion resistance
• Dirt-excluding check ball design for reliability
• Designed for ease of maintenance and replacement

Applications:
Used in GRACO high-pressure pumps for fluid transfer applications, including paint, lubrication, and other industrial fluid handling systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety of the pump system.
• Ensure the pump is depressurized before disassembly or replacement
• Clean the valve housing and seating surfaces before installing the new ball
• Inspect for wear or damage on both the ball and valve seat
• Follow GRACO’s recommended maintenance schedule for best results
