AeroShell Grease 7 is an advanced multi-purpose grease, composed of a synthetic oilÂ thickened with MicrogelÂ®, possessing good load carrying ability over a wide temperatureÂ range. It is inhibited against corrosion and has excellent resistance to water.Â The useful operating temperature range is â€“73Â°C to +149Â°C.
AeroShell Grease 7 satisfies nearly all the airframe grease requirements of turbine enginedÂ aircraft and also those of piston engined aircraft provided that seal incompatibility does notÂ occur. Most civil aircraft manufacturers approve AeroShell Grease 7 as a general purposeÂ grease either by brand name or by specification. It is recommended for lubricating highlyÂ loaded gears, actuator screw mechanisms, etc., also for instrument and general airframeÂ lubrication within the temperature range of â€“73Â°C to +149Â°C.
