This part of ISO 1179 specifies dimensions, performance requirements and test procedures for heavyduty (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.

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 second edition cancels and replaces the first edition (ISO 1179-2:2007), 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)

ISO 1179-2:2013(E)
Introduction

In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under

pressure within a circuit. In general applications, a fluid can be conveyed under pressure. Components

are connected through their threaded ports by fluid conductor connectors to tubes and pipes or to hose

fittings and hoses.

For threaded ports and stud ends specified in new designs in hydraulic fluid power applications,

ISO/TC 131/SC 4 recommends that the ISO 6149 series be used because these International Standards specify

ports and stud ends with metric threads and O-ring sealing and because the subcommittee would like to

help users by recommending one preferred system. ISO/TC 131/SC 4 further recommends that threaded

ports and stud ends in accordance with the ISO 1179 series, ISO 9974 series and ISO 11926 series not be

used for new designs in hydraulic fluid power applications; these International Standards are maintained

because they specify ports and stud ends that are currently used in hydraulic systems worldwide.

For threaded ports and stud ends specified in new designs in pneumatic fluid power applications,

ISO/TC 131/SC 4 recommends that ISO 16030 be used, except where products are to interface with

ISO 7-1 threads, because the subcommittee would like to help users by recommending one preferred

system. ISO/TC 131/SC 4 further recommends that threaded ports and stud ends in accordance with the

ISO 1179 series not be used for new designs in pneumatic fluid power applications; these International

Standards are maintained because they specify ports and stud ends that are currently used in pneumatic

systems worldwide.

Significant testing over more than 35 years of use has confirmed the performance requirements of

connection ends made from carbon steel. The stud end connections specified in ISO 1179-2, ISO 1179-3

and ISO 1179-4 apply to connectors detailed in ISO 8434-1, ISO 8434-2 and ISO 8434-4.
