GEARLINE EP GL-4

Rafinol Gearline EP GL-4 is high performance gear oil which has been specially developed for transmission, defferentials and axles working under medium and heavy conditions.

Usage

Rafinol Gearline EP GL-4 is a high-pressure gear oil developed for use in medium conditions for automotive differential manual gearbox and hypoid gears. It is used in passenger cars, trucks and construction equipment operating under high speed low torque, low speed high torque conditions.

Properties

  • Resistance Against Pressure: EP protects the surface by creating a thin film layer on the gear surface thanks to the overpressure feature.
  • Superior Foam Stability: Protects the lubricating film at operating temperatures and prevents corrosion.
  • Film Layer Activity: It prevents corrosion by forming a film on the metal surface with the corrosion additive contained in it.
  • High Heat and Oxidation Durability: It does not thicken during operation. Does not rust and sediment.
  • Resistance to Rust and Corrosion: It provides superior protection at high temperatures and prevents wear and corrosion.
  • Flow Characteristic at Low Temperature: It facilitates rudder movements with semi-synthetic structure due to flow is good even at low temperatures.
