High-Performance Aviation Lubricant - MIL-G-21164D AeroShell Grease 64 (formerly known as ASG 33MS) is an extreme-pressure synthetic airframe lubricant formulated with a lithium-complex thickener and fortified with 5% molybdenum disulphide. Specifically engineered for heavily loaded aircraft mechanisms, this product provides exceptional wear resistance, corrosion protection, and load-carrying capacity under demanding flight conditions. Manufacturer Part Numbers (MFG #) & Packaging Options: MFG #: 550072760 - 14oz Cartridge / Tube MFG #: 550043632 - 6 Lb Can MFG #: 550043636 - 37.5 Lb Pail Compatibility & AeroShell 17 Replacement This formulation serves as the direct alternative and official replacement for the discontinued AeroShell Grease 17. Note: When transitioning from a clay-based product (like ASG 17) to a lithium-complex grease, standard industry purging and cleaning procedures must be strictly applied. Key Benefits & Features for Aircraft Maintenance: Military-Grade Quality: Fully meets the stringent requirements of U.S. Military Specification MIL-G-21164D. Extreme Pressure (EP) Protection: Fortified with Moly to safeguard heavily loaded components against friction and premature wear. Superior Corrosion Resistance: Critical for airframe protection in harsh, humid, or maritime aviation environments. Water Washout Resistance: Maintains structural stability and premium lubrication effectiveness even when exposed to moisture. Wide Operating Temperature: Delivers excellent performance across the broad thermal ranges typical of high-altitude flight. Typical Aviation Applications: Heavily loaded gears in commercial and military landing gear mechanisms. Screw jacks, flap actuators, and stabilizer actuator systems. Sliding mechanisms and pivot points on aircraft control surfaces. General airframe lubrication points requiring a high-performance moly grease.
