Mobil Aero HF

Mobil Aero™ HF Series aviation hydraulic fluids are designed to meet the demanding requirements of commercial and military aircraft applications. These high quality formulations have a long history of excellent performance and provide long, trouble-free service over a wide range of operating conditions.

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

Reasons to trust Mobil Aero HF

• A high viscosity index (VI), which allows equipment operation over a wide range of temperatures
• Excellent low-temperature properties to provide high performance operation in low ambient conditions
• Good chemical and oxidation stability to resist the formation of acidic constituents, varnishes and deposits
• Meets "super clean" requirements of US Spec. MIL-PRF-5606 (Aero HF), ensuring reliable performance of pumps, servo-valves and other hydraulic system components

Applications

Mobil Aero HFA is a premium quality fluid that meets the quality requirements of the U.S. Military specification MIL-H-5606A (now obsolete). It has a very high VI and is suitable for use at temperatures down to -54 ºC (-65 ºF). While this quality fluid is no longer used by the U.S. Military, it is still used in some older, small private, and commercial aircraft. It is also used in industrial and commercial equipment requiring good fluidity at very low temperatures, where Mobil Aero HFA provides long, trouble-free service over a wide range of operating conditions.

Mobil Aero HF is a premium quality fluid that is approved against the most current version of U.S. Military specification MIL-PRF-5606. It has physical properties very similar to Mobil Aero HFA, and also meets "super-clean" requirements required by modern aircraft hydraulic systems. It is intended primarily for military aircraft, but it is also used as a hydraulic fluid for small private and commercial aircraft, and as a strut fluid in landing gear of large commercial aircraft. It is a NATO Code Number H-515 fluid.
