4. Introduction of YB/T4164

YB/T4164 is published for double wall brazed steel tubes (Bundy Tubes) used for refrigeration, A/C, general automotive, hydraulic and other similar applications requiring tubing of suitable quality for bending, flaring, forming, and brazing.


The dimensions, mechanical properties, requirements for coating, salt mist and double-flare tests of YB/T4164 are similar to US standards. While the chemical composition, flattening, bending, pressure proof tests and inside cleanliness of YB/T4164 are lower than that of US standards.


Generally the specifications of YB/T4164 are stricter than ASTM A254 and SAE J527.

The latest revisions of these standards are: YB/T4164-2007, ASTM A254-12, and SAE J527-201306.

Note: Please refer to the newest updates of these specifications.
