Specification for O-Ring Face Seal Connectors: Part 3 - Requirements, Dimensions, and Tests for Steel Unions, Bulkheads, Swivels, Braze Sleeves, Caps, and Connectors with SAE J1926-2 Inch Stud Ends
The three parts of SAE J1453 cover material, dimensional, and performance requirements of steel O-ring face seal (ORFS) connectors for tubing and the O-ring face seal interface and nut portion of hose stem assemblies for nominal tube diameters of 6 mm through 50 mm. SAE J1453-3 covers the requirements for O-ring face seal connectors to inch stud ends along with the associated adapters, bulkhead and union connectors. Inch hex dimensions of parts will be moved from the main document to an informative annex after 2013.
This revision of the standard adds size −32, corrects Table 2, adds the metric hex as the preferred option for new design, standardizes the nomenclature used in the tables and reorganizes tables from landscape to portrait mode.
In an effort to standardize within a global market and ensuring that companies can remain competitive in an international market, it is the intent to convert to metric hex sizes which will:
lead to one global system
guide users to preferred system
The optional inch hexes now contain the note “NOT TO BE USED FOR NEW DESIGN” in accordance with the Metric Hex Resolution approved during the March 2008 FCCTC meeting.
INCH HEX DIMENSIONS OF PARTS WILL BE MOVED FROM THE MAIN DOCUMENT TO AN INFORMATIVE ANNEX AFTER 2013 AND ONLY METRIC HEX DIMENSIONS OF PARTS WILL BE INCLUDED IN THE MAIN DOCUMENT
