The GRACO 25D165 is a repair kit containing PTFE (polytetrafluoroethylene) piston packings designed for use in GRACO displacement pumps. The kit is intended for replacing worn or damaged piston seals to restore pump performance, especially in applications requiring chemical resistance and higher temperature tolerance.

Key Features:

• Repair Kit (Piston Packings)
• 25D165 (for 290 cc displacement pumps)
• PTFE (polytetrafluoroethylene)
• Compatible with GRACO displacement pumps, specifically models requiring 290 cc piston repair kits (e.g., 19D954, 25D248, 25D155, 25D165)
• Chemical resistance
• High temperature tolerance
• Not ideal for abrasive applications
• Ease of maintenance (replaces entire piston packing stack)
• Reliable performance in demanding environments

Applications:
Used for maintenance and repair of GRACO displacement pumps in industrial, chemical, and high-temperature applications where chemical resistance and reliability are required.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and longevity of the equipment.
• Follow the equipment manual for detailed installation instructions.
• Ensure packings are installed with lips facing the correct direction (for piston packings: lips face up).
• Lubricate packings as recommended by GRACO.
• Replace all packings in the stack for optimal performance.
• Consult a GRACO specialist if unsure about compatibility or installation.
