BAC carries the most common hydraulic fluids used in corprate aircraft, including Mil-Spec 5606 in 5 gallon, 1 gallon, and quart sizes.     

Aviation hydraulic fluid is a vital component in the operation of an aircraft's hydraulic systems, which power essential functions such as landing gear, brakes, flight controls, and wing flaps. These specialized fluids are engineered to withstand extreme operating conditions, including high pressures, wide temperature ranges, and exposure to contaminants. Aviation hydraulic fluids are formulated to provide optimal lubrication, thermal stability, and resistance to oxidation and corrosion, ensuring reliable performance and longevity of hydraulic components. Meeting stringent industry standards, these fluids play a critical role in maintaining the safety, efficiency, and responsiveness of an aircraft's hydraulic systems, directly contributing to overall flight safety and operational excellence.

 

Aircraft Hydraulic Fluid Types

Aircraft hydraulic fluids are formulated to meet specific aircraft and system requirements. Selecting the correct hydraulic fluid should always be based on the aircraft or component manufacturer's approved specification. BAC supplies several commonly used aviation hydraulic fluids, including Skydrol, Royco, and HyJet products.

Hydraulic Fluid Type Common Specification Examples Typical Application
Mineral-Based Hydraulic Fluid MIL-PRF-5606 Royco 756 Hydraulic systems requiring a petroleum-based aviation hydraulic fluid
Fire-Resistant Hydraulic Fluid MIL-PRF-83282 Royco 782 Aircraft hydraulic systems requiring a high-temperature, fire-resistant hydraulic fluid
Phosphate Ester Hydraulic Fluid MIL-PRF-87257 / aircraft-specific specifications Brayco 881 Commercial and military aircraft hydraulic systems designed for phosphate ester fluids
Type IV Phosphate Ester Fluid Aircraft manufacturer and industry specifications HyJet IV-A Plus Aircraft hydraulic systems designed for Type IV phosphate ester hydraulic fluids

Important: Hydraulic fluids are not universally interchangeable. Always verify the aircraft, component, or equipment manufacturer's approved hydraulic fluid specification before selecting or replacing a fluid.
