AEROSHELL FLUID 12
AeroShell Fluid 12 is a low volatility synthetic ester oil used in aircraft
instruments and also for the general lubrication of aircraft. It is oxidation
and corrosion inhibited, and possesses good high and low temperature
characteristics.
APPLICATIONS
AeroShell Fluid 12 is used for general aircraft lubrication as well as for
aircraft gyro instrument gimbal bearings, separately lubricated high speed
turbines and compressors, aircraft air cycle equipment and electronic
equipment. AeroShell Fluid 12 is particularly suitable for use when an oil
with a low evaporation rate is required at high and low temperatures.
AeroShell Fluid 12 is a synthetic oil and it should not be used in contact
with incompatible seal materials such as neoprene or natural rubber.
Suitable seal material include Fluorocarbon (Viton). AeroShell Fluid 12 may
also affect certain paints and plastics. It is recommended that components
are evaluated for compatibility if there is any question.
