AeroShell Fluid 31 is a synthetic hydrocarbon-based aircraft hydraulic fluid with greatly improved fire resistance characteristics compared with conventional petroleum products. AeroShell Fluid 31 is dyed red. 31-1GL is recommended for use in aircraft, ordnance, and missile systems operating from –40°C to +205°C.

This fluid should be considered for use in auto pilots, shock absorbers, brakes, flight control systems, hydraulic servo-controlled systems and other systems using synthetic elastomer seals.
