Hydraulic oils with the designation HLP 10 are used as pressure fluids in industrial and mobile plants. They absorb high pressure (over 200 bar), protect against wear and thus prevent premature material ageing.

The designation HLP 10 is composed of the letter combination "HLP" and the number "10". DIN 51524-2 defines the properties of hydraulic oils with the designation HLP. These are hydraulic oils with anti-ageing and anti-corrosion additives as well as active agents for reducing friction and wear. The number 10 is a synonym for the kinematic viscosity of the hydraulic oil (in mm²/s) at 40 °C. The respective viscosity classes were specified in the ISO VG.

HLP 10 viscosity

The viscosity of HLP 10 is based on the defined viscosity class of ISO VG (International Organization for Standardization Viscosity Grade). This stipulates that the kinematic viscosity of the hydraulic oil must be between 9 and 11 mm²/s at 40 °C. The average viscosity is 10 mm²/s. Oils under ISO VG 10 are to be classified as very thin liquid and almost aqueous. The ISO VG classes range from 2 (very thin) to 1500 (high viscous).
