Overview
Krytox™ 283AD is a premium PFPE grease for aerospace, aviation, and defense applications where anticorrosion performance is required. Krytox™ 283AD is a heavy viscosity base oil with additional sodium nitrite for corrosion protection and anti-wear performance.
Krytox™ 283AD is a reliable, multipurpose aerospace grease for applications where failure is unacceptable across extreme temperatures. This performance aviation grease provides greater rust protection and nonevaporative performance compared to hydrocarbon-base lubricant solutions.
