Primary Chemistry:
Perfluoropolyether (PFPE)
Krytox™ 143AC is a PFPE-based synthetic oil for nonreactive, nonflammable, and long-lasting lubrication. Krytox™ 143AC is a fluorinated oil with a viscosity of 243 cSt (at 40°C) that is inert and safe in both chemical and oxygen service applications.
Krytox™ aerospace oils were engineered to withstand the incredibly harsh environments experienced in orbital flights in the vacuum of space.
Inferior lubricating oil protection in aerospace applications
Frequent and inefficient relubrication intervals
Thermal breakdown and deposit buildup from low-grade oils
Safety concerns or lubricant flammability
Krytox™ 143AC Oil is an aerospace-grade performance lubricant ideal for a wide variety of complex and sensitive applications, including but not limited to the following:
Bearings
O-ring and seal protection
Krytox™ Specialty Aerospace Performance Lubricants are PFPE based oils & greases that meet or exceed the strict requirements of the Aerospace, Aviation & National Defense industries.
