Castrol Tribol GR CLS 2 (previously called Olit CLS) is lithium/calcium based extremely water-resistant high performance grease. It protects against wear and is optimally suited for long-term application and long relubrication intervals. Its extreme resistance against water, caustic soda and detergents guarantees high operational reliability even under aggressive ambient conditions. In progressive centralized lubricating systems Tribol GR CLS 2 is easily pumpable and maintains its grease and long-term stability even under high operating pressures above 350 bar.
