Important Compatibility Consideration

AeroShell Grease 22 contains a synthetic hydrocarbon oil. Shell specifically cautions that it should not be used in contact with incompatible seal materials. Always verify lubricant and seal compatibility for the specific component before servicing.

Grease compatibility should also be considered before changing products. Shell advises that greases using different thickener types should generally not be mixed because the resulting mixture can have inferior physical properties or service performance. Follow the applicable maintenance documentation and manufacturer's recommendations when changing grease types.

AeroShell Grease 22 for MRO Maintenance

For MRO facilities and aircraft maintenance personnel, AeroShell Grease 22 is a useful option when an approved grease is required for demanding applications involving high loads, high speeds, elevated temperatures, or exposure to water. Its broad operating range and range of OEM and military specifications make it applicable across numerous aircraft lubrication requirements.

Before application, confirm the required grease specification, OEM approval, temperature limits, component requirements, and material compatibility in the applicable maintenance documentation.
