Understanding AS33514: The Aerospace Flareless Tube Standard

AS33514 is a critical technical standard published by SAE International that defines the dimensions and requirements for fitting ends used in flareless tube connections and gasket seals. Primarily used in the aerospace industry, it ensures that hydraulic and fluid system components can be interconnected reliably without the need for flaring the tube ends. Scope and Application as33514

The standard covers the specific design of fitting ends that interface with "flareless" systems. Unlike traditional flared fittings, these systems use a bite-type sleeve or a gasket seal to create a leak-proof connection. as33514

Strengths:

• Continued dominance in Central and Eastern European hosting.
• Gradual transition to 100GbE and 400GbE core links (already visible in DE-CIX peerings).
• Growing IPv6 adoption – important as IPv4 becomes scarcer.
