AEROSHELL FLUID 31
AeroShell Fluid 31is a synthetic hydrocarbon based aircraft hydraulic fluid
with greatly improved fire resistance characteristics when compared with
conventional petroleum products.
AeroShell Fluid 31has a specially designed base stock which imparts a
relatively high flash point, excellent low temperature properties and good
oxidation and thermal stability. In addition,AeroShell Fluid 31is formulated
with high technology additives to provide oxidation and corrosion
resistance, antiwear, and anti-foaming protection.
AeroShell Fluid 31is superclean filtered to ensure optimum performance in
particulate monitored systems.
AeroShell Fluid 31is dyed red.
The useful operating temperature range is –40 to +205°C.

APPLICATIONS
AeroShell Fluid 31is 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.
An increasing number of aircraft manufacturers now recommend use of this
type of fluid in aircraft hydraulic systems in preference to mineral hydraulic
oils. This move has been prompted by need to use fluids with better fire
resistant properties.
AeroShell Fluid 31is a synthetic hydrocarbon oil and should not be used in
contact with incompatible seal materials. Refer to the General Notes at the
front of this section for further information.

AeroShell Fluid 31is also approved for use in the Honeywell (formerly
Garrett) cooling turbine (cabin air compressors).
Increasingly this type of hydraulic fluid is being adopted for use in
hydraulic systems of military aircraft in place of mineral hydraulic fluids.
AeroShell Fluid 31is compatible with AeroShell Fluids 4, 41, 51, 61 and
71 and can be used in systems designed to operate with MIL-PRF-5606,
MIL-PRF-6083, MIL-PRF-87257 and MIL-PRF-46170 fluids.
Chlorinated solvents should not be used for cleaning hydraulic components
which use AeroShell Fluid 31. The residual solvent contaminates the
hydraulic fluid and may lead to corrosion.
