Applications

AeroShell Grease 7 satisfies nearly all the airframe grease requirements of turbine engine aircraft and those of piston engine aircraft provided that seal incompatibility does not occur. Most civil aircraft manufacturers approve AeroShell Grease 7 as a general-purpose synthetic grease either by brand name or by specification.

It is recommended for lubricating highly loaded gears, actuator screw mechanisms, etc., also for instrument and general airframe lubrication within the temperature range of –73°C to +121°C.
