ISO/FDIS 6149-4:2017(E) IntroductionIn fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) underpressure within an enclosed circuit. In general applications, a fluid can be conveyed under pressure.Components are connected through their threaded ports by stud ends on fluid conductor connectors totubes and pipes or to hose fittings and hoses. Fluid ports are closed by inserting a plug in the port. ISO 2017 – All rights reserved v
FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 6149-4:2017(E)Connections for fluid power and general use — Portsand stud ends with ISO 261 metric threads and O-ringsealing —Part 4:Dimensions, design, test methods and requirements forexternal hex and internal hex port plugsWARNING — The use of stud ends conforming to this document with ports conforming to therelevant parts of ISO 1179, ISO 9974 and ISO 11926 could lead to a hazardous situation.1 ScopeThis document specifies dimensions and performance requirements for external hex and internal hexport 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 bar1)).The permissible working pressure depends upon the plug end size, materials, design, workingconditions, 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 thisdocument to assure that components comply with the performance ratings.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document.

For use at pressuresand/or temperatures outside of this range, the manufacturer shall be consulted.Plugs conforming to this document may contain elastomeric seals. Unless otherwise specified, plugsare made and delivered with elastomeric seals for use within the specified working temperaturerange with petroleum-based hydraulic fluids. The use of these plugs and elastomeric seals with otherhydraulic fluids can result in a reduced working temperature range or can render the plugs unsuitablefor the application. Manufacturers may supply, upon request, plugs with elastomeric seals for usewith hydraulic fluids other than petroleum-based hydraulic fluids that meet the specified workingtemperature range of the plugs.2 ISO 2017 – All rights reserved

ISO/FDIS 6149-4:2017(E) 10 Manufacture10.1 ConstructionPlugs may be made from low-carbon steel by forging, cold forming or machined from bar stock, unlessotherwise recommended.10.2 WorkmanshipWorkmanship shall conform to the best commercial practice to produce high quality plugs. Plugs shallbe free from visual contaminants, all hanging burrs, loose scale and slivers that can be dislodged inuse, and any other defects that can affect the function of the parts. Unless otherwise specified, surfacefinish on all surfaces shall be Ra u 6,3 µm.10.3 FinishThe external surface and threads of all carbon steel parts shall be plated or coated with a suitablematerial that passes a 72 h neutral salt spray test in accordance with ISO 9227, unless otherwise agreedupon by the manufacturer and the user. Any appearance of red rust during the salt spray test on anyarea, except those noted below, shall be considered failure:— edges, such as hex points, serrations and crests of threads, where there can be mechanicaldeformation of the plating or coating typical of mass-produced parts or shipping effects;— areas where there is mechanical deformation of the plating or coating caused by crimping, flaring,bending and other post-plate metal forming operations;— areas where the parts are suspended or affixed in the test chamber where condensate canaccumulate. Internal fluid passages shall be protected from corrosion during storage.Cadmium plating is not allowed due to environmental concerns. Parts manufactured to this documentshall not be cadmium plated. Changes in plating can affect assembly torques and require requalification,when applicable.11 Procurement informationThe purchaser should supply a description of the plug using the designation in accordance with Clause 8when making an inquiry or placing an order. Deviations from the requirements of this document, suchas materials, pressures and temperatures, shall be agreed upon by the supplier and the purchaser.12 MarkingPort plugs shall be permanently marked with the manufacturer’s name or trademark.13 Identification statement (reference to this document)It is strongly recommended to manufacturers who have chosen to conform to this document that theyuse the following statement in test reports, catalogues and sales literature:“Port plugs conform to ISO 6149-4:—, Connections for fluid power and general use — Ports and studends with ISO 261 metric threads and O-ring sealing — Part 4: Dimensions, design, test methods andrequirements for external hex and internal hex port plugs.”4 ISO 2017 – All rights reserved
