The GRACO 15C638 is a PTFE encapsulated o-ring designed for use in GRACO equipment, specifically for sealing applications in 2:1 ratio transfer pumps. It is constructed with a PTFE (polytetrafluoroethylene) outer layer for enhanced chemical resistance and durability.

Key Features:

• O-Ring
• 2.1 in (length), 0.15 in (thickness)
• PTFE encapsulated
• For use with GRACO 2:1 ratio transfer pumps
• Enhanced chemical resistance due to PTFE encapsulation
• Durable construction for reliable sealing
• Designed for easy replacement and maintenance

Applications:
Used for sealing in GRACO 2:1 ratio transfer pumps, suitable for handling a wide range of fluids and viscous materials in commercial and industrial settings.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of equipment.
• Inspect the o-ring for damage before installation
• Ensure the sealing surface is clean and free of debris
• Lubricate the o-ring with a compatible lubricant if recommended by the manufacturer
