73585065 - Krytox GPL 206 High-Performance PFPE Grease, 8 oz Tube

Advanced PFPE Lubrication Technology

The Krytox GPL 206 8 oz Tube represents the pinnacle of lubrication technology for demanding industrial applications. Manufactured by Chemours (formerly DuPont), this grease is formulated from perfluoropolyether (PFPE) base oils and thickened with polytetrafluoroethylene (PTFE) powder. This unique chemical composition renders the grease completely non-flammable, chemically inert, and thermally stable up to 500°F (260°C). It is designed to perform where conventional hydrocarbon lubricants fail, offering a solution for critical systems that cannot afford downtime due to lubricant degradation.

One of the defining characteristics of Krytox GPL 206 is its compatibility with oxygen. Because the molecule is already fully oxidized, it cannot burn or support combustion, making it a standard choice for oxygen service equipment, valves, and regulators in the welding and medical gas industries. Furthermore, its chemical inertness means it will not react with aggressive acids, bases, solvents, or reactive gases. This makes it the ideal lubricant for chemical processing equipment where seal and bearing failures are common due to chemical attack.

The tribological properties of GPL 206 are excellent. It provides a thick, white, buttery consistency (NLGI Grade 2) that stays in place. It exhibits high load-carrying capability and excellent film strength, protecting metal surfaces from wear even under heavy loads. Unlike mineral oils or synthetic hydrocarbons, Krytox does not break down into tar or varnish at high temperatures; it simply volatilizes slowly over time, leaving no gummy residue behind. This ensures that bearings and moving parts remain clean and free-moving throughout their service life.

Compatibility is a major advantage of this product. It is safe to use with virtually all elastomers, plastics, and metals, including Neoprene, Viton, Silicone, and various thermoplastics that might swell or crack with standard petroleum greases. This universal compatibility simplifies maintenance inventories, as a single tube of GPL 206 can be used across a wide variety of sensitive components without fear of material incompatibility.
