The is a technical standard for a flareless tube connection fitting end, commonly used in aerospace hydraulic and fuel systems to ensure leak-proof seals under high pressure.
SAE-AS33514: A Guide to Aerospace Flareless Tube Fittings is an aerospace standard that defines the dimensions and requirements for male flareless tube fitting ends used in fluid systems. Originally developed for military applications under the designation MS33514 , the standard was transitioned to SAE International to ensure continued maintenance and relevance in the modern aerospace industry. Core Technical Purpose sae-as33514
. While you will still find it in plenty of existing aircraft (maintenance and repair), engineers are now directed to use alternative standards for modern projects. This makes it a "legacy" standard—essential for keeping older planes in the air but a relic for the next generation of aerospace design. 3.
