Connections for general use and fluid power - Ports and stud ends with ISO 261 threads with elastomeric or metal-to-metal sealing - Part 4 : dimensions, design, test methods and requirements for external hex and internal hex port plugs

ISO 9974-4:2006 specifies dimensions and performance requirements for metric external hex and internal hex port plugs for use with ISO 9974-1 ports. Port plugs in accordance with ISO 9974-4:2006 can be used at working pressures up to 63 MPa (630 bar). The permissible working pressure depends upon the plug end size, materials, design, working conditions, application, etc.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
