The GRACO 17F336 is a check ball kit containing four PTFE (polytetrafluoroethylene) check balls, each measuring approximately 1 5/8 inches in diameter. These balls are designed for use in GRACO diaphragm pumps, where they function as critical sealing and check valve components to control fluid flow direction and prevent backflow.

Key Features:

• Check Ball Kit
• 1 5/8 inch (approx. 1 11/16 inch may be referenced in some listings)
• PTFE (polytetrafluoroethylene)
• GRACO diaphragm pumps (e.g., ChemSafe series)
• High chemical resistance due to PTFE material
• Reliable sealing and check valve function
• Designed for easy replacement and maintenance
• Durable construction for extended service life

Applications:
Used in GRACO diaphragm pumps for handling a variety of fluids, including chemicals, antifreeze, detergents, gel-coat, and asphalt, where reliable check valve operation is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal pump performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Always shut off and depressurize the pump before replacing check balls
• Inspect the ball seat and housing for wear or damage during replacement
• Use only the specified number and size of check balls as per the pump manual
• Ensure proper alignment and seating of the check ball to prevent leaks and ensure reliable operation
