Sae-as33514 Extra Quality Online

SAE AS33514 is an aerospace standard that specifies the standard dimensions and requirements for flareless tube connection fitting ends and gasket seals. Overview of the Standard

The Business Case (Why You Should Care)

For Engineers: You get a reduction in warranty claims. By specifying AS33514, you move installation error from the "operator skill" column to the "design robustness" column.

History: This standard superseded the military specification MS33514. Associated Hardware sae-as33514

Connection Type: Primarily focuses on 24-degree cone flareless fluid connections, often rated for systems up to 3000 psi. SAE AS33514 is an aerospace standard that specifies

Years ago, the design team had a choice: use old-fashioned "flared" fittings that required the ends of metal tubes to be widened like a bell, or go with the modern AS33514 flareless standard. They chose the latter because AS33514 fittings use a "bite-type" sleeve that grips the tube without requiring it to be flared, making the assembly lighter and more resistant to the constant vibrations of jet engines.
