Sae-as33514 [exclusive]
Every circular cut must align perfectly with the middle axis of the fitting. Specification Details Connection Style Flareless Type Internal Cone Angle 24 Degrees Primary Material Choice High-grade Stainless Steel (like SS316L) Key Use Cases Hydraulic lines, high-temperature PTFE hoses
SAE-AS33514 isn't revolutionary because it handles higher pressure. It is revolutionary because it handles .
: Transferred and published by SAE in August 1998.
SAE International revises AS33514 roughly every 5–7 years. The latest revision (as of 2025) is , which clarified torque values for titanium tubes and added requirements for laser-etched traceability. sae-as33514
SAE AS33514 (formerly MS33514) is an aerospace standard that specifies the
This document is a reaffirmation of the older military specification MS33514 . While it was transitioned to an SAE standard, it remains mandatory for many Department of Defense (DoD) contracts.
The standard stays active through regular updates, such as the , to confirm it fits modern manufacturing needs. How Flareless Connections Work Every circular cut must align perfectly with the
: Dimensions are typically provided in inches, though metric equivalents may be included for informational purposes. 3. Applications in Industry
Cause: Differential thermal expansion between ferrule and tube (e.g., steel ferrule on aluminum tube). Solution: Retorque to specification after system reaches equilibrium. Consider using same-material tube and ferrule.
If you need help determining if your project should use this standard or its modern alternatives, I can compare the two, if you tell me what kind of machine or vehicle you are designing for. : Transferred and published by SAE in August 1998
While the full spec is technical (and behind SAE’s paywall), the core innovation revolves around and visual torque verification .
SAE AS33514 uses a . This design provides specific benefits:
defines several critical mechanical parameters to ensure leak-proof performance: Concentricity:
