Krytox 240AZ | Lubrication for Aerospace, Aviation & Defense Industries

MIL-SPEC PRF-26717 Type I & NSF H-1 rated; Superior Performance in Critical Applications

Krytox 240AZ grease is based on perfluoropolyether (PFPE) oils. These synthetic fluorinated lubricants are used in extreme conditions such as continuous high temperatures up to 149ºC and higher temperatures for shorter periods, depending on product grade limits. Chemically inert and safe for use around hazardous chemicals, these lubricants are non-flammable and are safe for use in oxygen service. Krytox oils and greases are silicone free and do not damage plastics or elastomers or cause corrosion to metals. They are commonly used as lubricants in aerospace, automotive, industrial and semiconductor applications as well as solving many other routine lubrication problems. Krytox greases are the original products that this military specification was written for and have been certified continuously since the specification was originally written. This is the latest data from the recertification that is required every five years. Krytox greases are standard as NLGI Grade 2 penetration. If the 240 AZ is ordered to meet MIL-SPEC requirements, it must be ordered as NLGI Grade 1 to meet the specification

Krytox 240AZ  – Advanced Chemistry for Advanced Applications

Applications for Krytox 240AZ lubricants are generally of a critical nature with temperatures in all industries reaching extremes for conventional lubricants. They are expected to be durable in the most aggressive environments and are now often considered an integral part of the design. Where failure of components is not an option, whether because of durability, warranty, safety, loss of productivity or down time, Krytox is the lubricant of choice in a wide range of industries and applications.

In the aerospace industry, Krytox 240AZ grease is applied in various settings spanning from bearings and sealants to o-rings and oxygen systems. Krytox is a valuable asset to the aerospace industry due to its superior performance in a wide range of temperatures scaling from -57 to 149ºC. In addition, it is robust in harsh environments and has excellent frictional properties, allowing it to resist change in properties over time, provide longer wear, and lower energy consumption. Krytox lubricants are compatible with all metals, elastomers, plastics, paints, and finishes. Due to the intense and severe circumstance of the aerospace industry, it can be expected that Krytox delivers a high level of product excellence.
