The GRACO 171868 is a replacement diaphragm designed for use in stainless steel, waterbase compatible pressure regulators. It is constructed with a PTFE (polytetrafluoroethylene) layer with nylon fabric and a Buna-N (nitrile rubber) base, providing chemical resistance and durability for demanding fluid handling applications.

Key Features:

• Diaphragm
• PTFE with nylon fabric/Buna-N base
• Stainless steel, waterbase compatible pressure regulators
• Chemical resistance due to PTFE and Buna-N materials
• Durable construction for reliable performance
• Designed for easy replacement and maintenance

Applications:
Used in industrial and commercial fluid handling systems where chemical resistance and reliable pressure regulation are required, particularly in applications involving water-based fluids and corrosive environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of the equipment.
• Ensure the regulator is depressurized before installation
• Inspect the diaphragm for damage or defects prior to installation
• Follow the equipment manual for specific installation procedures
• Regularly inspect the diaphragm for wear or chemical degradation
• Replace the diaphragm as part of routine maintenance or at the first sign of failure
• Use only GRACO-approved replacement parts for best results
