Sae-as33514 [best] Jun 2026

: The standard dictates critical measurements for concentricity, squareness, and surface roughness to prevent leaks under extreme vibration or pressure.

SAE AS33514 is a specialized aerospace standard that defines the dimensions and requirements for flareless tube connection fitting ends and gasket seals. saemobilus.sae.org

The "gasket seal" aspect is crucial for leak prevention. AS33514 defines the gland design—the area where the O-ring or seal is seated. This ensures the seal is not over-compressed or under-compressed, maintaining its structural integrity and sealing capability. 3. Surface Roughness and Concentricity sae-as33514

If you answer "yes" to all four, you have the right product for the job.

SAE-AS33514 is a published Aerospace Standard (AS) by SAE International (originally the Society of Automotive Engineers). Its full title is: "Sleeving, Markable, Heat-Shrinkable, Polyvinylidene Fluoride (PVDF), Crosslinked, for Wire and Cable Identification." AS33514 defines the gland design—the area where the

: Tooling marks on the sealing surface must comply with stringent roughness metrics. For instance, annular tool marks are strictly bounded—often to a maximum finish of 100 microinches Racap R sub a Surface Roughness and Concentricity If you answer "yes"

Manufacturers claiming compliance with SAE-AS33514 must subject their fittings to rigorous qualification testing:

: Primarily focuses on 24-degree cone flareless fluid connections, often rated for systems up to 3000 psi .

Always verify the dash number (e.g., -1 for 1/4”, -2 for 3/8”) and outlet flow orifice.

The standard originated as a United States Military Standard known as . It acted as a core design guideline for defense aviation components. In August 1998, the Department of Defense issued Notice 1 for MS33514G, officially cancelling the military document and superseding it with SAE-AS33514 to favor commercial off-the-shelf and industry-vetted standardization.
