Connections for fluid power and general use — Ports and stud ends with ISO 261 threads and O-ring sealing — Part 2: Heavy-duty (S series) stud ends — Dimensions, design, test methods and requirements

Scope

Stud ends in accordance with this part may be used at working pressures up to 63 MPa (630 bar) for non-adjustable stud ends, and 40 MPa (40 bar) for adjustable stud ends. The permissible working pressure depends upon the stud end size, materials, design, working conditions, application, etc. For threaded ports and stud ends specified in new designs in hydraulic power applications, only ISO 6149 rather than ISO 1179 and ISO 11926 is to be used.
