MIL-SPEC PRF-26717 Type 1,2, & 3, NSF H-1 rated

Krytox 240AC grease is based on perfluoropolyether (PFPE) oils. These synthetic fluorinated lubricants are used in extreme conditions such as continuous high temperatures up to 300 °C (572 °F) and higher temperatures for shorter periods, depending on product grade limits. Chemically inert and safe for use around hazardous chemicals, these lubricants are nonflammable 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 re-certification 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 240AC – Superior Performance, Temperature Stability, and Reduction in Wear

In the aerospace industry, Krytox 240AC grease is applied on 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 70 to 399ºC (–100 to 750 ºF). 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 circumstances of the aerospace industry, it can be expected that Krytox delivers a high level of product excellence.
