Krytox™ 283AB is a premium-performance perfluoropolyether (PFPE) grease with sodium nitrite additives for exceptional anticorrosion and anti-wear performance for critical aerospace and aviation lubrication. Krytox™ 283AB is formulated with a high-purity synthetic base oil that exhibits excellent thermal stability for extended use in high-temperature environments, especially compared to conventional mineral oil–based lubricants.
Krytox™ 283AB is a high-quality lubricant solution that is completely inert and nonflammable, delivering a heightened level of safety for complex and sensitive applications.
Migrating or poor grease or lubricant adhesion
Flammable or reactive grease chemistries
Excessive corrosion or rust on surface
Aerospace bearing and component damage or wear
Krytox™ 283AB is a lighter to medium of the premium AAND greases for use in applications that require additional corrosion inhibitors or additives to prevent rust formation.
