ISO 1179-2:2007 Connections for general use and fluid power - Ports and stud ends with ISO 228-1 threads with elastomeric or metal-to-metal sealing - Part 2: Heavy-duty (S series) and light-duty (L series) stud ends with elastomeric sealing (type E)
This part of ISO 1179 specifies dimensions, performance requirements and test procedures for heavy-duty
(S series) and light-duty (L series) stud ends with ISO 228-1 threads and the elastomeric sealing (type E) that
is used with them.
Heavy-duty (S series) stud ends with type E sealing in accordance with this part of ISO 1179 may be used at
working pressures up to 63 MPa (630 bar). Light-duty (L series) stud ends with type E sealing in accordance
with this part of ISO 1179 may be used at working pressures up to 25 MPa (250 bar). The permissible working
pressure depends upon size, materials, design, working conditions, application, etc.
Conformance to the dimensional information in this part of ISO 1179 does not guarantee rated performance.
Each manufacturer shall perform testing according to the specification contained in this part of ISO 1179 to
assure that components made to this part of ISO 1179 comply with the performance ratings.
NOTE 1 This part of ISO 1179 applies to connectors detailed in ISO 8434-1 and ISO 8434-2.
NOTE 2 The introduction of this part of ISO 1179 gives recommendations for ports and stud ends to be used for new
designs in hydraulic and pneumatic fluid power applications
