The bearings, gears, linkages, and actuators under the hood of your vehicle are sealed and lubricated for life. Fittings for re-lubrication do not exist, so the lubricants used in these applications must continue to perform over the life of the vehicle.

Krytox™ industrial lubricants provide maximum performance and durability across a wide range of applications, including alternators, cooling fan clutches, EGR valves, throttle bodies, motor-driven actuators, and highly-loaded drivetrain components, to minimize the risk of failures and warranty claims.

Consider these unique properties of Krytox™ industrial lubricants that are critical to automotive under hood applications:

  • A wide operating temperature range, from as low as -50°C to over 200°C, depending upon the grade.
  • Resistance to chemical attack by fuels, vapors, and aggressive combustion by-products that can compromise the life of most other lubricants.
  • Low volatility and durability during the life of the vehicle.
  • Compatibility with all plastics, elastomers and fluids used in today’s cars and trucks.
