Chemours Krytox™ AUT 2E68 PFPE Automotive Performance Lubricant
Categories: Fluid; Lubricant; Perfluoropolyether (PFPE)

Material Notes: Krytox™ AUT 2E68 grease was developed for the automotive industry’s need for lubricants that combine efficiency and performance at both high and low temperatures. These include such usages as viscous fan clutch bearings, alternators, throttle bodies, and other demanding applications.

Krytox™ AUT 2E68 grease has exceptionally low startup performance, but still provides low volatility, as well as outstanding thermal, oxidative, and corrosion resistance. Krytox™ oils and greases are based on perfluoropolyether oils and can be utilized in extreme conditions and environments.
