The GRACO 687057 is a V-packing seal made from graphite and PTFE (polytetrafluoroethylene), designed for use as a piston packing in GRACO Dura-Flo and similar pumps. Its primary function is to provide a reliable seal within the pump assembly, preventing leaks and ensuring efficient operation.

Key Features:

• V-Packing (piston seal)
• Graphite and PTFE (polytetrafluoroethylene)
• Compatible with GRACO Dura-Flo 1000cc and 1800 pumps (models such as 3A4100E and others as referenced in manuals)
• High chemical resistance due to PTFE
• Enhanced durability and sealing performance from graphite
• Designed for easy replacement and maintenance
• Reliable sealing for demanding industrial applications

Applications:
Used in industrial fluid handling and lubrication systems, particularly within GRACO Dura-Flo pumps for applications requiring robust sealing and resistance to harsh chemicals.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of the equipment.
• Install V-packings one at a time with the lips facing down for proper sealing
• Lubricate threads and seals as recommended in the manual
• Follow torque specifications for assembly components
• Regularly inspect and replace packings as part of routine maintenance
• Always use genuine GRACO replacement parts for critical seals
• Refer to the equipment manual for specific installation instructions
• Maintain a schedule for inspection and replacement of packings to prevent leaks and downtime
