Description
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
