Applications
  • Industrial and mobile hydraulic systems operating under heavy loads.
  • Construction and mining equipment, injection molding machines, and hydraulic presses.
  • Elevators, forklifts, and CNC machinery requiring ISO VG 68 hydraulic fluids.
  • Suitable for hydraulic systems exposed to moderate to high ambient temperatures.
Key Features & Benefits:
  • Superior Anti-Wear Protection
    Safeguards hydraulic pumps, motors, and valves by minimizing metal surface contact and reducing component wear.
  • Excellent Oxidation & Thermal Stability
    Resists oil breakdown at elevated temperatures, prolonging oil service life and reducing downtime.
  • Effective Rust & Corrosion Inhibition
    Provides outstanding protection against rust and corrosion, even in the presence of water.
  • Rapid Air Release & Anti-Foaming
    Prevents air entrainment and foam formation, ensuring smooth and efficient hydraulic operation.
  • Strong Demulsibility
    Quickly separates water from oil, maintaining system efficiency and preventing emulsification.
Health & Safety:

Avoid prolonged skin contact. Use gloves during handling. In case of contact with skin or eyes, wash immediately with clean water. Dispose of used oil responsibly and consult the Material Safety Data Sheet (MSDS) for further information.
