Aerospace (AS) grease fittings are manufactured to meet strict aerospace and military performance standards. These fittings are commonly used in aircraft, defense, and other critical applications where quality, traceability, and reliability are essential.
The “AS” designation refers to Aerospace Standards established by SAE International. Modern AS grease fittings are manufactured to SAE AS35411 standards, which replaced the older MIL-F-3541 military specification.
What’s Special About AS Grease Fittings?
Unlike standard commercial grease fittings, Aerospace (AS) grease fittings require extensive quality control and documentation throughout the manufacturing process.
AS grease fittings typically require:
- Detailed performance testing
- Dimensional inspection
- Material traceability
- Chemical and physical analysis
- Heat treat documentation
- Plating verification
- Certificates of conformance
These requirements help ensure consistent performance in aerospace and military environments where component reliability is critical.
AS Grease Fitting Materials and Configurations
Aerospace grease fittings are available in multiple materials and configurations depending on the application requirements.
Common options include:
- Corrosion resistant steel
- Stainless steel
- Monel
Available configurations include:
- Straight fittings
- 45-degree fittings
- 90-degree fittings
- Taper thread fittings
- PTF thread fittings
- Drive fittings
AS grease fittings are also available in multiple AS and NAS part number configurations for aerospace and military lubrication systems.
