Surfaces to be lubricated with Krytox™ L-Series lubricants should be thoroughly cleaned before the grease is applied to remove organic rust inhibitors that could inhibit proper lubrication. These lubricants are extremely inert and will keep their lubricating properties, even after long periods of storage.

Typical applications include all bearings, gears, valves, O-rings and any moving components, including robotics, in cleanroom and aerospace environments.

Krytox™ L-Series linear greases are compatible with all plastic and metal components typically used in industrial applications.

Krytox™ Greases

Krytox™ greases are nontoxic lubricants that maintain their lubricity and viscosity properties to reduce maintenance costs associated with re-lubrication, component failure, and downtime in demanding applications. They are created by thickening synthetic perfluoropolyether-based oil (PFPE) with polytetrafluoroethylene (PTFE) powder.
