AeroShell Fluid 31 is a synthetic hydrocarbon-based aircraft hydraulic fluid with greatly improved fire resistance characteristics. AeroShell Fluid 31 has a specially designed base stock that imparts a relatively high flash point, excellent low-temperature properties and good oxidation and thermal stability. In addition, AeroShell Fluid 31 is formulated with high-technology additives to provide oxidation and corrosion resistance, anti-wear and anti-foaming protection. AeroShell Fluid 31 is superclean filtered to ensure optimum performance in particulate monitored systems.
