In
44、 general applications, a fluid can 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 fittings and hoses. Fluid ports are closed by inserting a plug in the port. ISO 2017 All rights reserved vBS EN

46、for external hex and internal hex port plugs for use with ISO 6149-1 por t s.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, working conditions, application, etc.
