Hydraulic fluids

A hydraulic fluid is a type of oil whose key property is its incompressibility. What does hydraulic fluid do ? Its main function is to transmit energy from a pump to receiver units.


Hydraulic fluids also lubricate the metal components of the circuits involved (pumps, distributors, cylinders, etc.) and the characteristics of the hydraulic fluid are developed to suit the intended application: lubricity, heat transfer, prevention of wear, etc.


The main benefit is an increase in the service life of the components and a reduction in maintenance costs.

Hydraulic fluids are available in a range of viscosities.

Typical applications

  • Hydraulic damping of landing gear
  • Hydraulic circuits
