AeroShell Grease 7 Advanced Multi-Purpose Aircraft Grease

Protect your valuable aircraft parts from wear and tear with this advanced formula AeroShell Grease 7 aircraft grease. AeroShell 7 fights friction as a top quality airframe grease. It provides the perfect lubrication for piston or turbine engines and is especially recommended to lubricate actuator screw mechanisms, highly loaded gears and more. It works over a very wide temperature rage and withstands the elements.

AeroShell 7 grease is a synthetic ester that has been thickened with Microgel. Since it also contains clay, it shouldn't be mixed with soap-based grease. As for the AeroShell 7 mil. spec., it meets the standards of MIL-PRF-23827C, Type II, which means it has passed rigorous tests to perform well under harsh conditions. See the specifications for more information and the MSDS for safety and proper use instructions.
