Product Information
High-viscosity-index hydraulic oil with a low pour point and cold-weather fluidity. It provides anti-wear, rust and corrosion protection, foam control, air release, oxidation resistance and water separation. The brochure also describes compatibility with rubber seals.
Applications
For medium- and high-pressure hydraulic systems in engineering, construction, mining, steel rolling and plastics processing, particularly in cold regions or where temperatures change significantly. Also suitable for hydraulic systems of precision automatic machine tools used in winter.
