Scope

This part of GB/T 2878 specifies the dimensions and requirements of metric threaded oil ports for hydraulic drive connections, applicable to the stud end connections specified in GB/T 2878.2 and GB/T 2878.3. The maximum working pressure applicable to the oil ports specified in this part is 63 MPa (630 bar). The permissible working pressure should be determined based on factors such as the size of the oil port, the material, the structure, the working conditions, and the application. Users of this part should ensure that the materials surrounding the oil ports are sufficient to withstand the maximum working pressure.
