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 (see 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

ISO 6149-1:2022(E)
Introduction
In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure
within an enclosed circuit. In general applications, a fluid (liquid or gas) may be conveyed under
pressure.
Components are connected through their threaded ports by fluid conductor connectors to tubes and
pipes or to hose connectors and hoses.
Ports are an integral part of fluid power components, i.e. pumps, motors, valves, cylinders.
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, the ISO 9974 series and the
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
