The GRACO 189722 SEAT BALL is a small, precision-engineered component designed for use in GRACO diaphragm pumps, such as the Husky 1040 air-operated diaphragm pump. It is typically made from polypropylene, providing chemical resistance and durability. Its primary function is to act as a sealing element within the pump’s valve assembly, ensuring proper flow control and preventing backflow.

Key Features:

• Seat Ball
• Polypropylene (commonly used for this part type)
• Compatible with GRACO Husky 1040 air-operated diaphragm pumps and similar models
• Precision fit for reliable sealing
• Chemical-resistant material for durability
• Lightweight and compact design

Applications:
Used in GRACO diaphragm pumps for applications requiring reliable fluid transfer and sealing, such as in lubrication, chemical transfer, and industrial maintenance systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and compatibility with GRACO equipment.
• Ensure the pump is depressurized and isolated before installation.
• Inspect the seat ball and mating surfaces for wear or damage before installation.
• Follow the equipment manual for specific installation procedures.
