Scope

This document specifies the dimensions, performance requirements and test procedures for heavy- duty (S series) and light-duty (L series) s tud ends with threads, and the elas tomeric sealing (type E ) that is used with them as defined in ISO 228-1 . Heavy-duty (S series) stud ends with type E sealing in accordance with this document can be used at working pressures up to 63 MPa (630 bar) . Light-duty (L series) s tud ends with type E sealing in accordance with this document can be used at working pressures up to 25 MPa (250 bar) . The permissible working pressure depends upon size, materials, design, working conditions, application, etc. This document is applicable to connectors detailed in ISO 8434-1 , ISO 8434-2 and ISO 8434- 6. NOTE The Introduction gives recommendations for ports and stud ends to be used for new designs in hydraulic and pneumatic fluid power applications .
