ISO 6149-1:2006(E)
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 6149-1 was prepared by Technical Committee 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 6149-1:1993), which has been technically
revised.
ISO 6149 consists of the following parts, under the general title Connections for hydraulic fluid power and
general use — Ports and stud ends with ISO 261 metric threads and O-ring sealing:
⎯ Part 1: Ports with truncated housing for O-ring seal
⎯ Part 2: Dimensions, design, test methods and requirements for heavy-duty (S series) stud ends
⎯ Part 3: Dimensions, design, test methods and requirements for light-duty (L series) stud ends
— Part 4: Dimensions, design, test methods and requirements of external and internal hexport plugs

ISO 6149-1:2006(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, such as pumps, motors, valves, cylinders, etc.
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 end
