Synthetic high temperature grease


Castrol Tribol GR XT 2 HT (previously called Fire temp XT 2) is a high temperature polyurea thickened grease enhanced with Extreme Pressure (EP) additives as well as corrosion and oxidation inhibitors to provide a grease with outstanding lubricating properties. The fully synthetic, thermally stable structure enables long re-lubrication intervals at maximum operational reliability.


Tribol GR XT 2 HT is designed for rolling and sliding bearings at normal to medium peripheral speeds, and high operating temperatures in applications such as:

  • Heated bearings of dry calenders and dry cylinders
  • Fan bearings
  • Conveyor systems in paint lines
  • Autoclaves
  • Baking ovens
  • Continuous-flow drying ovens

Temperature application range: -25°C/-13°F to +180°C/+356°F. Short-term operation at higher temperatures is possible. Please contact your Castrol Technical Services team for further information.

  • Outstanding oxidation and thermal stability – provides reliable performance and good lubricant life in severe applications
  • Resistant to cold and hot water – the grease film remains on the surface, even in the presence of water
