The GRACO 192679 is a fluid-side diaphragm plate, typically constructed from PVDF (polyvinylidene fluoride), designed for use in GRACO air-operated diaphragm pumps. Its primary function is to support and secure the diaphragm assembly on the fluid side, ensuring proper pump operation and fluid containment.

Key Features:

• Diaphragm plate (fluid side)
• PVDF (polyvinylidene fluoride)
• Compatible with specific GRACO air-operated diaphragm pump models (refer to manual for exact compatibility)
• Durable PVDF construction for chemical resistance
• Precision fit for reliable diaphragm support
• Essential for maintaining pump integrity and preventing leaks

Applications:
Used in GRACO air-operated diaphragm pumps for transferring a wide range of fluids, including chemicals, paints, and other industrial liquids.

Installation Notes:

• Using genuine GRACO parts ensures optimal pump performance, longevity, and safety. Non-genuine parts may compromise pump reliability and void warranties.
• Follow the assembly order specified in the GRACO pump manual: install the air-side diaphragm plate, backup diaphragm (if applicable), diaphragm, fluid-side diaphragm plate, o-ring, and secure with the appropriate screw.
• Apply medium-strength (blue) thread locker to the threads of the diaphragm assembly for secure fastening.
• Ensure the correct orientation of all components as indicated in the manual (e.g., 'AIR SIDE' markings and flat side of plates facing the correct direction).
• Torque fluid-side diaphragm plates to 80–90 in-lb (9–10 N-m) at 100 rpm maximum, if specified for your model.
