Sae-as33514 Jun 2026

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

When purchasing or specifying SAE-AS33514 parts, look for the following identification on the manufacturer’s datasheet or certificate of conformance (C of C):

For new engineering designs, SAE International recommends using (Flareless Fitting End Design Standard) or (24° Cone Flareless Fluid Connection). Key Technical Specifications SAE AS33514 document sae-as33514

Cause: Damaged threads (cross-threading) or missing ferrule. Solution: Replace both nut and fitting body; never re-tap threads.

standard dimensions for a flareless tube connection and gasket seal SAE Mobilus Solution: Replace both nut and fitting body; never

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

The full title of SAE AS33514 is .

To appreciate SAE-AS33514, one must understand the problem it solved. Older fittings (e.g., SAE-AS4395, "flared" fittings) use a conical flare on the tube end to seal against a matching cone in the fitting body. While effective, flared fittings have two major weaknesses:

Interim updates addressing machining tolerances, thread profiles, and material enhancements. To appreciate SAE-AS33514, one must understand the problem
