Sae-as33514

Before AS33514, companies reported suspicious parts using internal spreadsheets, emails, or PDFs. This lack of uniformity led to:

AS33514 solves this by mandating a structured data report (often XML-based) that can be automatically ingested into industry databases like GIDEP (Government-Industry Data Exchange Program).

As avionics density increases and aircraft move toward more electric architectures (MEA), wire identification becomes even more critical. The latest revisions of AS33514 (currently Rev. C as of this writing) are incorporating:

However, the core PVDF, crosslinked chemistry remains unchanged because of its proven 50+ year track record in commercial flight.

In aerospace, a lost identification mark can lead to incorrect wire termination, maintenance errors, or even an in-flight malfunction. SAE-AS33514 provides the engineering community with a clear, testable, and enforceable standard for wire identification sleeves.

Whether you are designing a new harness for a UAV, repairing a legacy Cessna, or procuring parts for a 787 production line, specifying SAE-AS33514 compliant sleeving ensures that every label will outlast the aircraft itself.

Final Checklist for Engineers & Buyers:

If you answer "yes" to all four, you have the right product for the job.

Technical Report: SAE-AS33514 Standards The SAE-AS33514 is a critical aerospace standard that defines the dimensions and requirements for flareless tube connection fitting ends and gasket seals. It is widely used in high-pressure fluid systems, particularly in military and commercial aviation. 1. Scope and Purpose

This standard specifies the standard dimensions for fitting ends designed for:

Flareless Tube Connections: Used to join tubing without the need for flaring the tube end, which is essential for harder materials or high-vibration environments.

Gasket Seals: Provides specifications for the sealing interface to ensure leak-proof performance under varying pressures and temperatures. 2. Technical Specifications sae-as33514

Connection Type: Primarily focuses on 24-degree cone flareless fluid connections, often rated for systems up to 3000 psi.

Interchangeability: AS33514 fitting ends are designed to be compatible with other standard components, such as those defined in SAE-AS4395 or SAE-AS18280.

Measurement Units: Dimensions are typically provided in inches, though metric equivalents may be included for informational purposes. 3. Applications in Industry

SAE-AS33514 is frequently cited in broader military specifications (MIL-SPECS) for hydraulic and fuel systems:

MIL-DTL-5513: Utilizes AS33514 for specific fluid connection components in defense applications.

MIL-DTL-8789F: References this standard for fitting ends in aircraft engine lubrication systems. AS33514 solves this by mandating a structured data

Hose Assemblies: Often used in the assembly of PTFE hose systems where reliable, high-pressure seals are required. 4. Component Interaction

In a typical assembly, the AS33514 fitting end works in conjunction with:

A Sleeve/Ferrule: Which bites into the tube to create the seal.

A Coupling Nut: To apply the necessary torque and compression.
