The GRACO 191408 is a PTFE (polytetrafluoroethylene) diaphragm designed for use in GRACO surge tanks. It serves as a flexible barrier within the surge tank, separating the fluid from the gas charge and helping to dampen pulsation in fluid systems. This part is essential for maintaining efficient and reliable operation of GRACO surge tank equipment.

Key Features:

• Diaphragm
• 191408
• PTFE (polytetrafluoroethylene)
• Compatible with select GRACO surge tank models (specific models not listed for this part number)
• High chemical resistance due to PTFE material
• Designed for reliable separation of fluid and gas in surge tanks
• Supports efficient pulsation dampening in fluid systems

Applications:
Used in GRACO surge tanks for applications requiring pulsation dampening in fluid transfer systems, such as lubrication, paint, and chemical transfer.

Installation Notes:

• Using genuine GRACO diaphragms ensures optimal performance, safety, and longevity of the surge tank system.
• Follow the surge tank manual for diaphragm replacement procedures
• Ensure the surge tank is depressurized and drained before replacing the diaphragm
• Inspect the diaphragm and tank interior for damage or contamination before installation
• Use appropriate tools and safety equipment during installation
• Regularly inspect the diaphragm for wear or damage
• Replace the diaphragm as part of scheduled maintenance or if performance issues arise
• Refer to the GRACO surge tank manual for specific maintenance intervals and procedures
