Sae-as33514 | Real × 2026 |

In fluid systems, tubes carry liquids or gases under massive pressure. Traditional setups use a "flared" tube, meaning the end of the metal tube is stretched into a funnel shape.

Other SAE standards that work alongside AS33514 for tube and hose assembly include:

It is important for engineers and procurement officers to know that while the standard is active and supported, the since July 2008.

SAE AS33514 strengthens software assurance in safety-critical aerospace systems by formalizing planning, traceability, independence, and verification. Early adoption of its practices reduces certification risk and improves system safety.

The standard was originally derived from military specification MIL-M-81531 but has since evolved to meet modern commercial aviation standards, including those set by Boeing (BAC) and Airbus (ABS).

As part of the broader military specification reform movement in the late 1990s and 2000s, commercial entities assumed the stewardship of these parts. SAE International adopted MS33514G and re-published it with minor formatting modifications to match the aerospace technical library. In fluid systems, tubes carry liquids or gases

SAE AS33514 affects a wide range of industries, including:

Up at 70,000 feet, where the air is thin and the temperature drops to -60°F, the metal of the drone contracted. But the AS33514 held. The 37-degree cone, designed decades ago by engineers who obsessed over fractions of an inch, stayed pressed firmly against its seat.
