Description
The first Type V phosphate ester hydraulic fluid to be used in service on Airbus and Boeing aircraft, Mobil HyJet V has logged more than 10 million in-service hours in more than 2,500 aircraft since its introduction in 2008.
Compatible with all approved Type IV and Type V hydraulic fluids, elastomers and other hydraulic system materials, Mobil HyJet V is a fire-resistant phosphate ester hydraulic fluid that can help mixed fleets extend the life of hydraulic systems.
Mobil HyJet V is fully approved in all commercial 5000 psi hydraulic pressure aircraft systems. Reasons to trust in Mobil HyJet V
Reasons to trust in Mobil HyJet V
- Mobil HyJet V offers more than twice the shelf life of Type IV fluids, helping operators extend fluid life.
- It helps reduce fuel consumption and costs with its low-density formulation.
- Helps maximize component life and reduce maintenance costs with its exceptional protection against wear, corrosion, erosion and deposit control.
- Gives operators a high measure of safety and confidence with its exceptional resistance to flammability, which exceeds Grade A flash point specifications of air framers such as Airbus and Boeing.
- Maintains outstanding performance, stability and viscosity in a wide range of temperatures.
Features and Benefits
Mobil HyJet V offers the following key features and benefits:
