Connections for fluid power and general use - Ports and stud ends with ISO 261 metric threads and O-ring sealing - Part 4: Dimensions, design, test methods and requirements for external hex and internal hex port plugs (ISO 6149-4:2017)

ISO 6149-4:2017 specifies dimensions and performance requirements for external hex and internal hex port plugs for use with ISO 6149‑1 ports.
Port plugs in accordance with this document can be used at working pressures up to 63 MPa (630 bar[1]). The permissible working pressure depends upon the plug end size, materials, design, working conditions, application, etc.
Conformance to the dimensional information in this document does not guarantee rated performance. Each manufacturer is expected to perform testing according to the specification contained in this document to assure that components comply with the performance ratings.
WARNING: The use of stud ends conforming to this document with ports conforming to the relevant parts of ISO 1179, ISO 9974 and ISO 11926 could lead to a hazardous situation.
[1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

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
on the ISO list of patent declarations received (see 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.

This document was prepared by ISO/TC 131, Fluid power systems, SC 4, Connectors and similar products
and components.
This second edition cancels and replaces the first edition (ISO 6149-4:2006), of which it constitutes a
minor revision.
The main change since last version is the addition of a warning statement about the hazards of
intermixing of stud ends with the various port types.
