BIO Hydraulic Oil HFDU Fire-resistant

LUBECO™ Hydraulic Oil FR HFDU is a high performance, fire-resistant, readily biodegradable hydraulic fluid based on synthetic esters. A special additive package delivers excellent extreme pressure properties, thermal oxidation resistance, anti-wear and non-foaming control.

A very high Viscosity Index of Hydraulic Oil FR HFDU provides extremely wide operating temperature range.

Hydraulic Oil FR HFDU allows for very long oil-change intervals resulting in cost effectiveness and CO2 emissions reduction. Produced in viscosity classes ISO VG 15/22/32/46/68/100

Industry Performance Standards

  • HFDU: ISO 6743/4

Areas of Application

Hydraulic Oil FR HFDU is specifically designed for use in all hydraulic systems, both hydrostatic and hydrodynamic. Hydraulic Oil FR HFDU is recommended for hydraulic applications in environmentally sensitive areas with a high fire risk – immediate vicinity of potential flame or heat sources. Hydraulic Oil FR HFDU is particularly used in mining, power generation, railway and power line maintenance, construction, earth moving and other industries.

Characteristic Features

  • Very good fire-resistance – reducing possibility of ignition in case of fluid leakage;
  • Ultimate performance and anti-wear protection;
  • Outstanding thermal oxidation stability;
  • Extra high Viscosity Index - wide operating temperature range;
  • Long oil-change interval > reduction in CO2 emissions;
  • Non-toxic, readily biodegradable



ISO-VG viscosity classification ISO VG 46
Base Oil Synthetic oil
Kin. viscosity at 40 °C The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. 46 cSt
Density at 15 °C 920 kg/m3
Kin. viscosity at 100 °C 9,5
Viscosity Index Viscosity Index (VI) is a measure of the change of viscosity with temperature. The higher the VI, the less is the viscosity affected by changes in temperature. >190
Flash Point >320 °C
Pour Point The pour point of a liquid is the temperature below which the liquid loses its flow characteristics. -40 °C
FZG Test >12
Iodine Value <10
Biodegradability in 21 days >90 %
