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™ 240AD is the highest viscosity grease in the 240 series. With a viscosity of 1540 at 20°C and a viscosity of 502 at 38°C it is ideal for applications that require a thick grease. This grease does not meet the MIL SPEC.
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™ 250AD grease is black a grease that contains molybdenum disulfide added as an extreme pressure additive for highly loaded gears and bearings. Highest viscosity in the 250 Series with a viscosity of 502 cSt at 38°C and 44 cSt at 99°C. Temperature range is -29 to 316°C.
Krytox™ AGL Series
Krytox™ AGL 683
Krytox™ AGL 683 grease contains extreme pressure and anticorrosion additives for applications in corrosive atmospheres or with significant shock loading where an element experiences greater mixed film or boundary lubrication than full film or hydrodynamic lubrication. Krytox AGL 683 grease will also provide superior performance in applications prone to significant fretting corrosion.
Krytox™ AUT Series
Krytox™ AUT 2045
Krytox™ AUT 2045 is a white grease based on perfluoropolyether (PFPE). PFPE lubricants demonstrate outstanding product life and unequaled performance. AUT 2045, like most greases, combines the base oil with polytetrafluoroethylene (PTFE) powder as a thickener. The use of PFPE as a base oil provides superior chemical and thermal stability to all grease product lines.
Krytox™ AUT 2245
Krytox™ AUT 2245 grease addresses a broad range of applications from O-ring to bearing lubrication over a wide temperature range where corrosion is a potential issue. It is thickened with polytetrafluoroethylene (PTFE) and contains sodium nitrite, a traditional anti-corrosion additive.
Krytox™ AUT 2A45
Krytox™ AUT 2A45 grease is formulated with soluble additives that exhibit excellent resistance to water washout, repel moisture, and provide extra protection from corrosion of metal parts and bearing surfaces. With no solid additives, bearings run quieter and wear less, extending bearing and component life.
Krytox™ LVP/ VPF Series
Low pressures. Extremely high or low temperatures. Hostile environments. Whatever special needs your system might have, Krytox™ low vapor pressure (LVP) high-vacuum grease works—safely, reliably, and cost-effectively.
Aerospace & Aviation Oils
Krytox 143 series oils are clear, colorless, fluorinated synthetic oils that are non-reactive, nonflammable, safe in chemical and oxygen service, and are long lasting.
Krytox™ 157 FS Series
Krytox™ 157 FSH
Like the other Krytox™ fluorinated oils, Krytox 157 FS lubricant is insoluble in most common organic solvents. It is also nonflammable. Decarboxylation occurs on heating above about 170 °C (338 °F) and becomes vigorous at 200 °C (392 °F). The product formed appears to be a mixture but is mainly a hydro-endcapped version of Krytox fluorinated oil. The decarboxylation of its alkali metal salts in the presence of water occurs at lower temperatures and yields essentially pure polymers end capped with hydrogen.

Krytox™ Corrugator Series
Krytox™ 226 FG Corrugator Grease
Corrugator Krytox™ 226 FG and Corrugator Krytox 227 FG provide you with peace-of-mind and full confidence that Krytox™ greases are non-toxic, and completely biologically and environmentally inert.
Krytox™ 227 FG Corrugator Grease
Krytox™ 240AB is a MIL PRF-27617 TYPE II greases. It is also NSF H-1 Rated for incidental food contact. Viscosity @ 20°C is 240 cSt and Viscosity @ 38°C is 86 cSt. The 240AB is ideal in -40 to 232°C environments.
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.
Krytox™ 250AC EP grease is a black grease that contains molybdenum disulfide added as an extreme pressure additive for highly loaded gears and bearings. It has a viscosity of 270 cSt at 38°C and 26 cSt at 99°C. Temperature range is -34 to 288°C
Krytox™ 250AZ grease is a black grease that contains molybdenum disulfide added as an extreme pressure additive for highly loaded gears and bearings. Lowest viscosity in the 250 series with a viscosity of 24.7 cSt at 38°C and 4.2 cSt at 99°C. Temperature Range is -57-149°C.
Krytox™ 283 series anticorrosion greases are white greases that contain sodium nitrite. These grades provide rust protection at ambient temperatures, corrosion protection at high temperatures, and anti-wear protection. Krytox 280 Series contain 1% sodium nitrite.
