BS ISO 8434-2:2007

1   Scope This part of ISO 8434 specifies general and dimensional requirements for the design and performance of 37° flared connectors that are suitable for use with ferrous and non-ferrous tubes with outside diameters from 6 mm to 50,8 mm, inclusive. These connectors are for use in fluid power and general applications within the limits of pressure and temperature specified in this part of ISO 8434. They are intended for the connection of tubes and hose fittings to ports in accordance with ISO 6149-1, ISO 1179-1, ISO 9974-1 and ISO 11926-1. (See ISO 12151-5 for related hose fitting specification.) These connectors provide full-flow connections with metal-to-metal sealing in hydraulic systems operating to the working pressures shown in Table 1. Because many factors influence the pressure at which a system performs satisfactorily, these values shall not be understood as guaranteed minimums. For every application, sufficient testing will need to be conducted and the results reviewed by both the user and manufacturer to ensure that required performance levels are met.

   NOTE 1  For new designs in hydraulic  fluid power  applications, see the requirements given in 9.6. Where the requirements of the application allow for the use of elastomeric seals,  connector  designs that conform to International Standards and incorporate elastomeric sealing are preferred.
