If you file an AS33514 compliant report, it must include:
The relationship between the thread and the hex face must not exceed specified tolerances when measured at specific diameters.
: Flareless tube connection with an external thread and a 24° internal cone. Applications
SAE AS33514 outlines a set of requirements for components used in aerospace applications, including: sae-as33514
Originally derived from the United States military standard MS33514 , this aerospace standard is published and routinely updated by SAE International under the supervision of the G-3 Aerospace Couplings, Fittings, Hose, and Tubing Assemblies committee. Historical Evolution: From MS33514 to SAE-AS33514
: The baseline adoption by SAE International.
: SAE AS33514E is published, representing the current technical baseline for tracking historical implementations and ongoing compliance documentation. If you file an AS33514 compliant report, it
The "bite" mechanism of the sleeve/ferrule provides an excellent seal at high pressures.
is an authoritative engineering standard that defines the exact measurements for fluid system connections used in military and aerospace applications. Managed by SAE International , this standard outlines the crucial dimensions for flareless tube connections and gasket seals to prevent high-pressure fluid leaks in high-stakes environments like airplanes and defense equipment. What is SAE AS33514?
He pulled his inspection mirror. The fitting was an old design, a relic of a previous revision. He checked his digital tablet against the updated engineering order. The spec had been changed: the old MS33514 standard had been superseded by the . Historical Evolution: From MS33514 to SAE-AS33514 : The
Would you like a comparison with the newer (miniature pressure regulator) or guidance on testing/certification for an AS33514 valve?
As of 2026, the standard is maintained, with versions like SAE-AS33514E (published April 2019) providing updated specifications.
