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 Follow GRACO equipment manual for specific installation procedures
