4 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 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 4, Connectors and similar products and components. ISO 8434 consists of the following parts, under the general title Metallic tube connections for fluid power and general use: Part 1: 24 cone connectors Part 2: 37 flared connectors Part 3: O-ring face seal connectors Part 6: 60 cone connectors with or without O-ring This corrected version of ISO :2009 incorporates the following corrections: In Figure 2, the tolerance on the 60,5 angle has been corrected from ± 5 to ± 0,5. In Figure 7, key item 1, thread minor diameter has been corrected to thread major diameter. In Table 13, a ref. tolerance has been added to dimension L 30 and a min. tolerance has been added to dimension s 3. In Table 16, the tolerances for four of the five dimensions have been corrected. iv ISO 2009 All rights reserved

5 Introduction In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure within an enclosed circuit. In general applications, a fluid can be conveyed under pressure. Components can be connected through their ports by connections (connectors) and conductors (tubes and hoses). Tubes are rigid conductors; hoses are flexible conductors. ISO/TC 131/SC 4 recommends that connectors that conform to ISO and ISO be used because these International Standards represent the state of the art. However, ISO has been developed because it specifies connectors that are currently used worldwide. This part of ISO 8434 is based on British standard BS The threads for the 60 cone connection are pipe threads conforming to ISO ISO 2009 All rights reserved v
