The GRACO 108839 is a PTFE (polytetrafluoroethylene) diaphragm designed for use in GRACO air-operated diaphragm pumps. It serves as a critical sealing and flexing component, ensuring reliable fluid transfer and preventing leaks within the pump assembly.

Key Features:

• Diaphragm
• PTFE (polytetrafluoroethylene)
• Compatible with GRACO air-operated diaphragm pumps (specific models not listed)
• High chemical resistance due to PTFE material
• Designed for durability and long service life in demanding environments
• Essential for reliable pump operation and leak prevention

Applications:
Used in GRACO air-operated diaphragm pumps for transferring a wide range of fluids in industrial, manufacturing, and maintenance applications.

Installation Notes:

• Using genuine GRACO diaphragms ensures optimal pump performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Follow the equipment manual for specific installation procedures
• Ensure all mating surfaces are clean and free of debris before installation
• Inspect diaphragm for damage or defects prior to installation
• Use recommended lubricants and tools as specified in the manual
• Regularly inspect diaphragms for wear, cracks, or chemical degradation
• Replace diaphragms at recommended intervals or when signs of wear are detected
• Keep spare diaphragms on hand for quick replacement and minimal downtime
