Mobil Aero HFA and HF are formulated for aircraft systems where use of hydrocarbon-based hydraulic fluids is required. They are low viscosity products, high VI (viscosity index) fluid with excellent low temperature properties, good anti-wear performance, and good chemical stability. Mobil Aero HFA and HF are composed of mineral base oil stock and contain shear-stable VI improvers.

 Aero HF Aviation Hydraulic Fluid Features:

• High Viscosity Index (VI)
• Excellent low temperature properties
• Good chemical and oxidation stability  
  
• Meets "super clean" requirements of U.S. Spec. MIL-PRF-5606 (Aero HF)   
  
• Allows equipment operation over a wide range of temperatures
• Provides high performance operation in low ambient conditions
• Resists the formation of acidic constituents, varnishes, and deposits
• Ensures reliable performance of pumps, servo-valves and other hydraulic system components
