Sae-as33514 Jun 2026

The SAE-AS33514 standard originated directly from the United States military specification . As part of the Department of Defense’s standardization initiatives, many "Military Standard" (MS) sheets were transferred to civil standards organizations like SAE International to simplify supply chains and maintain unified technical baselines. Revision History

In simple terms, SAE-AS33514 specifies how to make a leak-proof, vibration-resistant fitting without using a traditional flare. This "flareless" design is a game-changer for durability and maintenance.

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

AS33514 defines the geometric parameters and tolerance ranges for the fitting end to work with this mechanism. This standard focuses on and does not address material selection.

Installation requires standard wrenches rather than specialized, high-capacity flaring equipment. Status and Future Design Considerations The SAE-AS33514 standard originated directly from the United

Maintaining leak-tight security under severe multi-axis vibration requires tight geometric dimensioning and tolerancing (GD&T). AS33514 imposes strict manufacturing limits:

Preferred in applications needing robust, standardized components, as they often supersede military specifications (e.g., MIL-F-55060). This "flareless" design is a game-changer for durability

While the full SAE AS33514 document is the definitive source, its core focus is on standardizing the geometry of the fitting end to ensure proper sealing and interchangeability. The standard defines critical features such as:

Therefore, for all modern applications,

The specifications ensure the fitting sits correctly within a corresponding port, typically complying with other SAE standards like AS4395.
