hydraulic fluids
Liquid power medium
Hydraulic fluids are liquids used to transmit power in hydraulic systems—machinery that converts fluid pressure into mechanical force.
These fluids flow through pumps, valves, and cylinders in equipment like excavators, aircraft landing gear, and car brakes.
Most hydraulic fluids are petroleum-based oils, though synthetic and water-based alternatives exist for specific applications.
The fluid must resist compression, lubricate moving parts, and withstand high temperatures without breaking down.
