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.
