Sae-as33514 Direct
However, the core PVDF, crosslinked chemistry remains unchanged because of its proven 50+ year track record in commercial flight.
is a critical aerospace standard published by SAE International that defines the standard dimensions, tolerances, and design requirements for fluid system fitting ends utilizing flareless tube connections and gasket seals. Primarily deployed within military aircraft, defense systems, and commercial aerospace engineering, this document establishes strict manufacturing baselines to prevent fluid leakage under high vibration, intense thermal cycling, and medium-to-high pressure environments.

For new engineering designs, SAE International recommends using (Flareless Fitting End Design Standard) or (24° Cone Flareless Fluid Connection). Key Technical Specifications SAE AS33514 document
High-pressure fluid lines require precise, smooth surfaces to prevent leak paths. The standard defines requirements for surface finish (smoothness) and concentricity (alignment of the fitting components), which are essential for mitigating stress concentrations that can lead to failure. Applications of SAE-AS33514 Technical Definition and Core Function of the dimensions
When a mechanic tightens the connection, a small metal sleeve or ferrule bites into the outer wall of a straight tube.
The standard covers tube outside diameters (OD) ranging from 3/16 inch up to 2 inches. Common sizes include: smooth surfaces to prevent leak paths.
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.
