Mobil HyJet™ V: The Premier Hydraulic Fluid for Aviation

Mobil HyJet™ V , the aviation industry’s first Type V phosphate ester hydraulic fluid, has been a trusted choice for Airbus and Boeing aircraft since its introduction in 2008. With over 10 million in-service hours across more than 2,500 aircraft, Mobil HyJet™ V sets the benchmark for hydraulic fluids in commercial aviation.

This fire-resistant phosphate ester hydraulic fluid is fully approved for all 5000 psi hydraulic pressure systems in commercial aircraft. Compatible with Type IV and Type V fluids, elastomers, and other hydraulic system materials, Mobil HyJet™ V is engineered to extend hydraulic system life, even in mixed fleets. Its outstanding thermal and hydrolytic stability significantly reduces fluid degradation compared to Type IV fluids, leading to longer in-service life and lower maintenance costs.
