If you are looking to purchase components, ensure they meet the latest revision, such as SAE-AS33514E , for compliance.
establishes requirements and recommended practices for software assurance activities in safety-critical systems. It complements functional safety processes (e.g., DO-178C) by focusing on risk mitigation, verification independence, and lifecycle traceability.
Rather than relying on a flared tube system (which structurally alters the shape of the pipe end), AS33514 details a . The system operates by drawing a sleeve tightly against the tube wall during assembly, cutting a microscopic groove or "bite" into the outer diameter of the tubing to secure a high-integrity, metal-to-metal seal. This connection is backed by an integrated gasket seal zone to ensure secondary protection against zero-tolerance micro-leaks. Historical Origins: The Evolution from MS33514 sae-as33514
Additionally, each production batch must undergo a : a tube fitted with the assembly is pulled axially until the tube yields or the joint slips. The slip load must exceed the tube's yield strength.
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. If you are looking to purchase components, ensure
The standard establishes precise dimensional data and qualification requirements for fitting ends used in fluid systems. It is heavily utilized in military and defense applications and was originally adapted directly from the U.S. military specification Primary Application: Flareless tube connections and gasket seals. Current Status: As of July 2008, this standard is inactive for new designs Replacement Standards:
Simplifies installation, especially in tight spaces, by eliminating the need to flare thin-walled tubing. Rather than relying on a flared tube system
Ensuring a component's fitting end conforms to SAE AS33514 requires verification. While SAE International is the authoritative source for the standard, certification can be confirmed through other means.
The new standard for fittings isn’t just about threads—it’s about reducing risk.
