Krytox 283AD: Developed for Aerospace and Aviation

Krytox 283 AD  was developed with aerospace applications in mind.  Krytox lubricants were initially developed by DuPont in the early 1960s specifically for the precise and demanding lubrication needs of the aerospace industry. Krytox synthetic lubricants have since replaced hundreds of special-formula, hydrocarbon-based oils and greases throughout the aerospace and aviation industries, thanks to a long list of superior performance characteristics and certifications.

Suborbital, orbital and deep space flight – require ironclad reliability and lifetime lubrication for critical components that must operate flawlessly in high vacuum and extreme temperatures, as well as endure exposure to fuels, oxidizers and radiation.

Commercial, corporate and military aviation – demands safety, reliability and compliance with a wide range of precise military specifications, as well as reduced maintenance requirements.

Krytox aerospace greases are available in grades conforming to/applicable under:

• • • MIL PRF-27617
    • CAGE Code No. 50JY2 (manufacturing)
    • CAGE Code No. 43S57 (business)
    • FSN, NSN #9150-01-008-0498
    • NATO #G-398

Krytox 283AD: Advantages of an Aerospace Grade Lubricant

Krytox perfluoropolyether- (PFPE-) based oils and greases, including Krytox 283 AD, provide a remarkable list of properties for aerospace applications, including:

• Unaffected lubricity and viscosity within a wide temperature range: -70 °C to 399 °C (-100°F  to 750 °F)
• Stable physical properties over time – Krytox lubricants are virtually unaffected by harsh environments like shock, vibration, heat, pressure and caustic chemicals such as rocket fuels and oxidizers, as well as being radiation resistant
• Resistance to vapor loss in a vacuum, such as during high altitude, orbit or deep space flight
• Excellent friction-reduction characteristics provide long wear and low energy consumption
• Compatible for use with most metals, elastomers, plastics, paints and finishes
• Nontoxic, non-flammable, inert and non-evaporative
• World-class technical consultation tailored to the needs of the aerospace community
