SAE J1453的三个部分涵盖了管道用钢制O形环面密封（ORFS）连接器的材料、尺寸和性能要求，以及公称管道直径为6 mm至38 mm和公称软管直径为6.3 mm至38 mm的软管杆组件的O形环面密封接口和螺母部分。SAE J1453-2涵盖了“基于公制”的O形环面密封连接器到公制螺柱端以及相关适配器、隔板和接头连接器的要求。本标准中使用公制六角扳手平面。

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 38 mm and for nominal hose diameters 6.3 mm through 38 mm. SAE J1453-2 covers the requirements for “metric based” O-ring face seal connectors to metric stud ends along with the associated adapters, bulkhead and union connectors. Metric hex wrenching flats are used throughout this standard.
