The gasket seal offers superior sealing against leaks compared to purely metal-to-metal seals. Conclusion
It seals tightly without needing to bend, stretch, or flare the actual tube ends.
These dash numbers are critical when cross-referencing with other SAE standards like AS33515 (fittings for flexible hose).
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.
: Unlike flared fittings that require the tube end to be widened, flareless fittings use a sleeve or ferrule that bites into the outer diameter of the tube, creating a mechanical seal. sae-as33514
This standard superseded the military specification MS33514 . Associated Hardware
Never attempt to mate an SAE-AS33514 flareless fitting with an SAE-AS4395 flared component. The sealing geometry is entirely different, leading to immediate leakage.
"Secured," Kael said, pushing off the hull. "Mark the maintenance log. AS33514 installed. Ready for re-pressurization."
The $1B Problem of Bad Parts Every year, the global aerospace industry loses an estimated $1 billion to counterfeit electronic components. A single fake resistor, capacitor, or IC can cause an in-flight system failure, trigger a costly recall, or ground an entire fleet. The gasket seal offers superior sealing against leaks
SAE AS33514 is an active aerospace standard that defines the dimensions and design requirements for a specific type of male fitting end used in flareless tube connections. Essentially, it provides the "recipe" for manufacturing fitting ends that can create a leak-proof seal without requiring the tube to be flared, often utilized in high-pressure hydraulic and pneumatic aircraft systems. Evolution and Context
, often referred to simply as AS33514 , is a standard developed by SAE International (Society of Automotive Engineers). It specifically defines the fitting end, standard dimensions for flareless tube connection and gasket seal .
Flareless (commonly referred to as "bite-type" fittings).
The specifications ensure the fitting sits correctly within a corresponding port, typically complying with other SAE standards like AS4395. If you need help determining if your project
In plain English: It’s a fitting standard designed for humans.
AS33514 defines a specific type of used in continuous-flow oxygen systems. Unlike diluter-demand systems, continuous-flow systems provide a constant flow of oxygen to the mask (adjustable by the user). The valve reduces high-pressure cylinder storage (up to 400 psig) to a usable outlet pressure (50 psig) and includes integral gauges for monitoring.
Engineers and manufacturers adhere to strict dimensional data and quality notes within the AS33514 standard to ensure part interchangeability:
