液压传动连接 带米制螺纹和O形圈密封的油口和螺柱端 第4部分：六角螺塞
Application Summary AI generated
This standard specifies the dimensions, materials, and performance requirements for hex plugs used in hydraulic fluid power systems. It is applied to seal threaded ports and stud ends with metric threads and O-ring sealing, ensuring leak-proof connections in hydraulic equipment such as industrial machinery, mobile hydraulics, and fluid power systems. The standard is critical for maintenance, assembly, and replacement of sealing components in high-pressure hydraulic circuits.
