The GRACO 166026 SEAL, PISTON is a PTFE (polytetrafluoroethylene) piston seal designed for use within GRACO pump assemblies, specifically to ensure a tight, reliable seal between moving parts in high-pressure fluid handling equipment.

Key Features:

• Piston Seal
• PTFE (polytetrafluoroethylene)
• Compatible with GRACO pump assemblies, such as the Monark series
• High chemical resistance due to PTFE material
• Designed for durability and reliability in high-pressure environments
• Ease of maintenance and replacement as part of routine service

Applications:
Used in GRACO pump assemblies for sealing pistons in fluid transfer and spray equipment, commonly found in industrial, agricultural, and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of equipment.
• Remove the displacement rod from the cylinder before replacing the seal.
• Check for wear or damage on related components (e.g., ball, seat, o-ring) during replacement.
• Grease packings and ensure proper alignment during installation.
• Refer to the equipment manual for detailed disassembly and reassembly instructions.
