HyJet™ V Outstanding stability and more than twice the fluid life of Type IV hydraulic fluids help extend equipment life and reduce maintenance costs
Many of today’s commercial aircraft hydraulic systems require a fire-resistant fluid that offers greater stability, better wear protection and stronger corrosion control than Type IV hydraulic fluids can provide. Approved for all Airbus and Boeing aircraft, HyJet™ V offers mixed fleets: • R esistance to acid formation at a wide range of temperatures, allowing for more than twice the fluid in-service life as compared to Type IV fluids • O utstanding deposit control and protection against rust, wear and corrosion, helping to extend the life of hydraulic systems • F lammability that exceeds Airbus and Boeing Type V, Grade A, flash point specifications Since its introduction in 2008, more than 2,500 aircraft have operated on HyJet V. That’s more than 10 million in-service hours on all key commercial aircraft types. HyJet V: • F irst Type V fluid authorized for use in the Airbus A380’s 5000-psi hydraulic system
Airline operators using HyJet™ V have reported cost savings due to less frequent component replacements and maintenance interventions.
• C ompatible with all approved Type IV and Type V hydraulic fluids, elastomers and other hydraulic system materials
HyJet V may be used in aviation hydraulic fluid applications specifying:
• L ow density, as compared to competitive Type IV hydraulic fluids, helping to lower fuel consumption and aircraft weight

HyJet™ V – Performance Longer In-Service Life
Better Wear Protection
The Airbus NSA 307110 Ampoule Test measures a fluid’s resistance to reaction with water (hydrolytic stability) and molecular breakdown at high temperatures (thermal stability).
The Four Ball Wear Test (ASTM D 4172) determines the lubricity and wear protection properties of a lubricant.

Side-by-side testing confirmed that HyJet™ V offers better stability and longer in-service life than Type IV fluids.
Stronger Corrosion Control The ASTM D 665A test identifies rust on polished steel rods that have been exposed to 10 percent water in fluid for 24 hours at 60°C. Rust Protection Comparison

The Four Ball Wear Test (ASTM D 4172) produced generally smaller scars for HyJet™ V than for samples of other Type IV and Type V commercial products. The difference in wear protection performance between HyJet V and the competitive Type V product was especially pronounced.
