Straight threads must be perfectly cut so they mate easily with parts like the Eaton Aeroquip PTFE hose fittings .

For decades, the Department of Defense relied on MS33514G (Military Sheet 33514) to control fluid port geometries. These ports were foundational to Cold War-era aviation engineering.

For engineers, the use of AS33514 is mandatory to ensure a component is designed to the correct, interface-critical dimensions. For procurement professionals, referencing this standard in purchase orders is non-negotiable to guarantee that the parts received will physically fit and function as intended in the aircraft's fluid systems.

is a critical aerospace standard that defines the dimensions, tolerances, and design requirements for flareless tube connection fitting ends and gasket seals . Administered by SAE International , this standard plays a foundational role in military and commercial aviation fluid conveyance systems, ensuring zero-leakage performance under extreme pressures and vibration. sae-as33514

The gasket seal offers superior sealing against leaks compared to purely metal-to-metal seals. Conclusion

Fluid distribution lines in aerospace systems—such as hydraulic lines, fuel linkages, and coolant conduits—must remain completely sealed against grueling structural demands. The SAE-AS33514 standard addresses this by regulating the specific physical geometry of the male and female adapter connection points.

The standard covers tube outside diameters (OD) ranging from 3/16 inch up to 2 inches. Common sizes include:

SAE AS33514 is an active aerospace standard that defines the dimensions and design requirements for a specific type of male fitting end used in flareless tube connections. Essentially, it provides the "recipe" for manufacturing fitting ends that can create a leak-proof seal without requiring the tube to be flared, often utilized in high-pressure hydraulic and pneumatic aircraft systems. Evolution and Context For the most recent revisions and specific dimensional

AS33514 continues to be the valid standard for maintenance, repair, and overhaul (MRO) of systems that were originally designed with it.

As aviation evolves toward more electric and hydrogen-powered aircraft, the role of hydraulic fittings may diminish—but not disappear. High-pressure hydraulic systems remain essential for primary flight controls on large aircraft and will continue for decades in existing fleets.

For modern projects, engineers are directed to use AS4375 (Flareless Fitting End) or AS5863 (24° Cone Flareless Fluid Connection). Technical Specifications

SAE AS33514 is a standard developed by the Society of Automotive Engineers (SAE) for the aerospace industry. The standard outlines the requirements for the design, testing, and validation of components used in aerospace applications, including electrical, electronic, and electromechanical (EEE) components. The standard is specifically focused on the qualification and testing of components for use in harsh environments, such as those found in aircraft, spacecraft, and missile systems.
