What Is a Hydraulic Fluid?
Any hydraulic system requires a hydraulic fluid to allow power transfer. These low and non-compression fluids also provide lubrication, cooling, and corrosion resistance to help the system operate its best. Hydraulic fluids have evolved over the years, with adaptations reducing the risk of flammability first posed in the 1940s. A range of these hydraulic fluids have been adopted by both commercial and military aircraft as a number conform to military specifications.
These products are not just confined to the aviation industry. Many of our industrial hydraulic fluids are compatible in other areas due to their advantageous properties, including:
- Low freezing point
- Good anti-foam properties
- Good low and/or high-temperature stability
Aerospace Hydraulic Fluid
Hydraulic fluids can be divided into three main categories:
- Petroleum-based hydraulic fluids have strong lubrication, anti-foaming, and anti-rusting but are highly flammable and more likely to degrade.
- Water-based hydraulic fluids have good heat capacity and electrical conductivity while being non-flammable, but are more compressible and bacteria-prone than other options.
- Synthetic hydraulic fluids can be tailored for specific applications with good service life and biodegradability, but they are more expensive and offer less versatility.
Our on-demand catalogue has many other options within these product families, including Type IV and Type V phosphate ester fluids. Some notable AeroShell hydraulic fluids have been discontinued; in those cases, our knowledgeable support team will help you find a satisfactory replacement.
