本SAE标准涵盖了管道用钢制O形圈面密封配件的材料、尺寸和性能要求，以及公称直径为6.35 mm（0.250 in）至38.1 mm（1.500 in）的软管或软管杆组件的O形圈面密封接口和螺母部分。这些配件用于工业设备和商业产品上的一般应用和液压系统，其中弹性体密封件可以克服泄漏和装配过程中的变化。这些配件能够在从95 kPa（28 in Hg）真空到工作压力的液压系统中提供防泄漏的全流连接 表1 由于许多因素影响液压系统将或不将令人满意地执行的压力，这些值不应被解释为保证的最小值。对于任何应用，建议用户和制造商进行充分的测试和审查，以确保所需的性能水平是安全的。看 图1 . 使用SAE J1453软管杆连接或成型管连接的流体导体组件的额定工作压力 图32a ，不得超过其最低额定部件的额定工作压力。

This SAE Standard covers material, dimensional, and performance requirements of steel O-ring face seal fittings for tubing and the O-ring face seal interface and nut portion of hose stem assemblies for nominal tube or hose diameters 6.35 mm (0.250 in) through 38.1 mm (1.500 in). These fittings are intended for general application and hydraulic systems on industrial equipment and commercial products, where elastomeric seals are acceptable to overcome leakage and variations in assembly procedures. These fittings are capable of providing leak-proof full flow connections in hydraulic systems operating from 95 kPa (28 in Hg) vacuum to working pressures shown in Table 1 . Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, these values should not be construed as guaranteed minimums. For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and manufacturer to assure that required performance levels will be safe. See Figure 1 . The rated working pressure of a fluid conductor assembly using SAE J1453 hose stem connections or formed tube connection per Figure 32a , shall not exceed rated working pressure of the lowest rated component thereof.
