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.
