Key Features:

• Guide/Shift Saddle
• Acetal
• Compatible with GRACO air-operated diaphragm pumps, such as the Husky 715 series
• Durable acetal construction for wear resistance
• Facilitates smooth shifting and alignment within the pump
• Essential for reliable pump operation and maintenance

Applications:
Used in GRACO air-operated diaphragm pumps for applications requiring reliable fluid transfer, such as industrial lubrication, chemical processing, and mining operations.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of the equipment.
• Grease the inside surfaces of the shift saddle before installation
• Hold the link assembly firmly in place during installation
• Install the screw and torque to 7–9 in-lb (0.8–1.0 N·m)
