Exxon HyJet V Aviation Hydraulic Fluid-55GL
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.
