This standard is critical for aircraft oxygen systems, particularly in general aviation, business jets, and some military trainer/transport aircraft.
SAE AS33514 is a technical standard published by SAE International (originally the Society of Automotive Engineers). Its formal title is
The following standards are cited within SAE AS33514, meaning their requirements are integral to its application: sae-as33514
In the demanding field of aerospace engineering, fluid systems reliability is paramount. High-pressure hydraulic and fuel lines require robust connections that can withstand vibration, temperature extremes, and immense pressure without leaks. One of the industry-standard specifications governing these connections is , "Fitting End, Standard Dimensions for Flareless Tube Connection and Gasket Seal."
: AS33514 fitting ends are designed to be compatible with other standard components, such as those defined in SAE-AS4395 or SAE-AS18280 . This standard is critical for aircraft oxygen systems,
| Standard | Material | Primary Use | Marking Method | | :--- | :--- | :--- | :--- | | | Crosslinked PVDF | Permanent wire identification | Thermal transfer, dot matrix, laser | | AS23053 | Various (including PVDF) | General purpose electrical insulation | Not required | | AS81044 | Crosslinked ETFE | Wire insulation (hookup wire) | Not applicable | | AS5942 | PTFE or FEP | High-temperature sleeving (non-markable) | Hand writing only |
The "Caliber" Rapid-Release Shackles Context: Deep Space Orbital Maintenance Yard, Sector 4. : The current active version released in April 2019
: The current active version released in April 2019. Technical Design and Sealing Mechanism 1. Flareless Connection Design
Note: While the standard is maintained actively under SAE AS33514E for legacy and active aircraft procurement contracts, it is marked as "Inactive for New Design" in favor of newer fluid connection geometries like AS4395. Design and Geometric Specifications
For engineers, procurement specialists, and MRO (Maintenance, Repair, and Overhaul) technicians, SAE-AS33514 is more than a document; it is the definitive standard governing the performance and qualification of (commonly known as wire markers or Kapton® sleeves).
