Krytox™ L-15 G Grease

Krytox™ L-15 G Grease is a proprietary formulation based primarily on a perfluoropolytrimethyleneoxide with the same excellent thermal properties of Krytox™ and much improved temperature viscosity performance.


Product Overview

Krytox™ L-15 G Grease linear perfluoropolyethers (PFPEs) provides exceptional low volatility characteristics for longer lubricant life.  The base oils have high viscosity indexes to provide effective lubrication over a wider temperature range. They have the excellent chemical and thermal stability of all Krytox™ products and are nonflammable and safe for use in oxygen and other harsh chemical environment

Features & Benefits

Krytox™ L-15 G Grease is compatible with most materials including the most commonly used plastics and elastomers.  It is safe for use around fuels and oxidizers and has excellent load carrying capacity. It is designed for performance in extreme vacuum or temperature conditions.


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.
