Red Line 80402 CV-2 Synthetic Grease
                        

Red Line’s team of chemists formulate fully-synthetic lubricants using only the world’s finest base stocks. At Red Line, it’s not designed to be the cheapest – it’s built to be the best. Red Line only uses superior polyester-based products – resulting in lubricants that are extremely stable at high temperatures.

Synthetic CV-2 grease provides excellent water resistance, low temperature flow, and its very high melting point allows it to be used in high temperature wheel bearings, high angle and conventional CV-joints, chassis lubrication and many industrial applications.

  • Outperforms the best conventional or synthetic greases and lubes
  • Excellent high-temp stability, extreme-pressure protection, and water resistance
  • Used in a variety of applications with operating temps from -100°F to 500°F
  • Strong resistance to oxidation and corrosion, low evaporation and oil separation with a minimum effect on rubber seals
  • Contains an organic moly for chassis lubrication and high temp/high speed industrial equipment
  • Synthetic fluidity allows increases in bearing life up to 200%
  • Contains a red moly compound which is a superior lubricant to black moly disulfide lubricants
