Since the first commercial application over 50 years ago, Krytox™ 240 synthetic lubricants have delivered consistent, superior, extended performance. Today, with new additives for new challenges, Krytox lubricants continue to deliver extreme performance under extreme conditions. Krytox is the lubricant of choice for demanding conditions, high and low temperatures, extreme pressure, and harsh environments.
240 series greases are white buttery greases with all of the same properties as our 143 series oils that they are made from, but they are in grease form.
Krytox 240 AZ, 240 AB and 240 AC are MIL PRF-27617 greases. If 240 AZ is ordered to meet MIL-SPEC requirements, it must be ordered as NLGI Grade 1 to meet the specification.
Krytox™ 240AA grease is the second least viscous grease in the Krytox 240 Series. The only grease less viscous is the Krytox 240AZ. 240AA has a viscosity of 60 cSt at 20°C and 24.7 cSt at 38°C it is ideal for low viscosity grease applications. Ideal temperature range of Krytox 240AA is -51 to 177°C.
Krytox™ 240 AZ is a MIL PRF-27617 TYPE I grease. It also has NSF H-1 rating for incidental food contact. If Krytox 240 AZ is ordered to meet MIL-SPEC requirements, it must be ordered as NLGI Grade 1 to meet the specification. Krytox 240AZ is the lowest viscosity grease of the 240 series greases. Ideal for applications that require a very low viscosity grease. Temperature is -57 to 149°C.
Krytox™ 240AC is a MIL PRF-26717 TYPE III and NSF H-1 Rated grease. It also meets many ASTM specifications. Krytox 240AC has a viscosity of 800 at 20°C and 270 cSt at 38°C making it ideal in situations where a high viscosity grease is required. The ideal temperature of this grease is -34 to 288°C.
