ExxonMobil's Mobil HyJet V is a fire-resistant hydraulic fluid made of phosphate ester that is compatible with Type IV and Type V hydraulic fluids, elastomers and other materials used in hydraulic systems. With its greater stability, better wear protection and stronger corrosion control, it offers more than twice the fluid life of Type IV hydraulic fluids. Since its introduction in 2008, Mobil HyJet V has generated over 10 million in-service hours. It is the first Type V phosphate ester hydraulic fluid used in service for Airbus and Boeing aircraft.
