Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received. www.iso.org/patents

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

The committee responsible for this document is ISO/TC 131, Fluid power systems, Subcommittee SC 4,

Connectors and similar products and components.

This third edition cancels and replaces the second edition (ISO 1179-2:2013), which has been technically

revised.

ISO 1179 consists of the following parts, under the general title Connections for general use and fluid

power — Ports and stud ends with ISO 228-1 threads with elastomeric or metal-to-metal sealing:

— Part 1: Threaded ports

— Part 2: Heavy-duty (S series) and light-duty (L series) stud ends with elastomeric sealing (type E)

— Part 3: Light-duty (L series) stud ends with sealing by O-ring with retaining ring (types G and H)

— Part 4: Stud ends for general use only with metal-to-metal sealing (type B)
Changes from previous edition:
— Deleted Annex A and removed references to the Annex.
— Deleted Introduction and incorporated relevant content into Note 2 of Scope

— Added Interchangeability Warning concerning the hazards of intermixing of stud ends with various

port types
— Added material requirements for elastomeric seal

— Replaced Test Methods, Test Report, and Re-Use of Components with the equivalent requirements

of ISO 19879.
— Figures 1 and 2 were redrawn.

DRAFT INTERNATIONAL STANDARD ISO/DIS 1179-2:2022(E)
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)
1 Scope

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 can 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 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.

Conformance to the dimensional information in this part of ISO 1179 does not guarantee rated

performance. It is the responsibility of each manufacturer to perform testing according to the

specification contained in this part of ISO 1179 in order to ensure 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, ISO 8434-2, and ISO 8434-6.

NOTE 2 This part of ISO 1179 is not recommended in new designs. For threaded ports and stud ends specified

in new designs in hydraulic fluid power applications the ISO 6149 series should be used. For threaded ports and

stud ends specified in new designs in pneumatic fluid power applications the ISO 16030 should be used, except

where products are to interface with ISO 7-1 threads.
