ISO 6149-3:2006(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 6149-3 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 6149-3:1993), 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 6149-3:2006(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 stud ends on fluid conductor connectors to tubes

and pipes or to hose connectors 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 will be maintained

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

INTERNATIONAL STANDARD ISO 6149-3:2006(E)
Connections for hydraulic fluid power and general use — Ports
and stud ends with ISO 261 metric threads and O-ring
sealing —
Part 3:
Dimensions, design, test methods and requirements
for light-duty (L series) stud ends
1 Scope

This part of ISO 6149 specifies dimensions, performance requirements and test procedures for metric

adjustable and non-adjustable light-duty (L series) stud ends and O-rings.

Stud ends in accordance with this part of ISO 6149 may be used at working pressures up to 40 MPa

[400 bar ] for non-adjustable stud ends and 31,5 MPa (315 bar) for adjustable stud ends. The permissible

working pressure depends upon the stud end size, materials, design, working conditions, application, etc.

Conformance to the dimensional information in this part of ISO 6149 does not guarantee rated performance.

Each manufacturer should perform testing according to the specification contained in this part of ISO 6149 to

assure that components comply with the performance ratings.

NOTE 1 A significant number of tests have been conducted to confirm the performance requirements of connection

ends made from carbon steel.

NOTE 2 This part of ISO 6149 applies to connectors detailed in ISO 8434-1 and ISO 8434-2 (see ISO 12151-4 for

related hose fitting specification).

NOTE 3 The Introduction of this part of ISO 6149 gives recommendations for ports and stud ends to be used for new

designs in hydraulic fluid power applications.
