Overview
Krytox™ AUT 2245 Grease addresses a broad range of applications from O-ring to bearing lubrication over a wide temperature range where corrosion is a potential issue.
Krytox™ AUT 2245 anticorrosion grease is a high-performance lubricant solution based on ISO 100–grade synthetic perfluoropolyether (PFPE) oil thickened with polytetrafluoroethylene (PTFE) and enhanced with sodium nitrite anticorrosion additive. Krytox™ AUT is engineered as a multipurpose lubricant for automotive equipment and heavy transportation parts, such as viscous fan clutch bearings, alternators, and idler bearings.

Features & Benefits
- Unsurpassed oxidation resistance of base oil: PFPE will not oxidize and gum up with age and use
- Will not break down with high temperatures experienced in electric motors
- Operating temperature range from –44 to 200°C (–47 to 392°F)
- Advanced PTFE thickener: Special high-efficiency thickener will not oxidize or break down with shear
- Lubed-for-life potential: Typically, there is no need to relubricate bearings during the lifetime of the electric motor
Problems Solved
Poor solutions with poor corrosion prevention
Automotive component or bearing wear and damage from standard grease
Inferior grease stability at high engine temperatures
Incompatibility with lubricant and elastomer seals
Applications
Krytox™ AUT 2245 anticorrosion grease can be used in a wide range of applications, including the following:
Reducing noise, vibration, and harshness (NVH) and squeak in industrial and commercial vehicles
Automotive components, fan clutch bearings, alternators, and idler bearings
