SKU: HYJETV-55GL Category: Tag: Brand:

Description

SAE AS1241 Exxon HyJet V Aviation Hydraulic Fluid-55GL

Exxon HyJet V is a Type V fire-resistant phosphate ester hydraulic fluid, which is superior in thermal and hydrolytic stability to commercially available Type IV hydraulic fluids.

Better stability means the extent of fluid degradation in aircraft systems will be less than Type IV fluids, in-service fluid life will be longer, and consequently aircraft operator maintenance costs may be lower.

Features & Benefits SAE AS1241 Exxon HyJet V Aviation Hydraulic Fluid-55GL

HyJet V provides excellent high and low temperature flow properties (kinematic viscosities) and rust protection. HyJet V has also demonstrated an improvement over the erosion protection performance afforded by Type IV fluids.

Exxon HyJet V offers the following key features and benefits:

Features Advantages and Potential Benefits
Higher stability than Type IV fluids Longer fluid life,
Lesser need to replace fluid due to degradation,
Reduced hydraulic system maintenance costs
Meets Boeing BMS 3-11 and SAE AS1241 Type IV and Type V requirements Improved flammability characteristics over meeting just the Type V requirements
Low density Reduced weight of the hydraulic fluid carried by aircraft,
Reduced aircraft fuel consumption,
Lower operating costs
Excellent rust protection Reduced risk of equipment damage in the event of major water contamination
Excellent low and high temperature viscosity balance Precise hydraulic system control and response even during extended range/polar flights,
Longer aircraft hydraulic system equipment life
Excellent deposit control Longer aircraft hydraulic system equipment life,
Reduced maintenance costs
Improved protection against electro-chemical corrosion (erosion) Protection against servo valve and pump damage
Fully compatible with all approved Type IV and Type V phosphate ester hydraulic fluids Flexibility in use by airline operators
