Sae-as33514 - Work

Whether you are designing a new harness for a UAV, repairing a legacy Cessna, or procuring parts for a 787 production line, specifying SAE-AS33514 compliant sleeving ensures that every label will outlast the aircraft itself.

Ensuring the center of the fitting is perfectly aligned with the tube. Squareness: Making sure the end is cut at a perfect 90-degree angle. Surface Roughness:

. SAE International adopted it to bring it under the umbrella of civilian aerospace standards while maintaining nearly identical dimensions for consistency across military and commercial aviation. 2. The "In-Active" Status , the standard was declared inactive for new designs

But what if a standard could engineer that error out of the system?

The standard specifies all critical interface dimensions, including:

is a critical aerospace technical standard issued by SAE International that establishes the definitive fluid system interface configuration for flareless tube connections and gasket seals . Originally integrated into United States military systems under the designation MS33514 , this standard regulates the strict geometry, dimensional tolerances, and design criteria required to ensure leak-free performance in high-pressure aircraft hydraulic, pneumatic, and fuel transport systems. Whether you are designing a new harness for

Incorporates a defined undercut zone near the base of the external UNJ controlled-radius threads, allowing the component to be seated flush against a gasket seal or boss face.

is a cornerstone of reliability in the aerospace world. It bridges the gap between critical engineering theory and practical, real-world application. For any professional working with high-performance fluid systems, knowing this standard is essential for ensuring that the nuts, bolts, and fittings work together as a perfectly integrated whole.

SAE International has periodically reviewed and updated this standard to stay in alignment with modern manufacturing capabilities: Surface Roughness:

The standard dictates the maximum allowable deviation between the thread and the face of the hex. Surface Finish: Roughness must comply with ASME B46.1

Actual pressure ratings depend on tube material (typically 304 stainless steel, 321 stainless, or aluminum alloy 6061-T6) and tube wall thickness.

is an aerospace standard that specifies the dimensions and design requirements for flareless tube connection fitting ends and gasket seals. It is a critical specification for ensuring the compatibility and performance of fluid systems, particularly in military and defense applications where it was originally adopted from military specifications.
