BS ISO 8434-6:2009 Metallic tube connections for fluid power and general use. 60° cone connectors with or without O-ring
BS ISO 8434-6 specifies general and dimensional requirements for the design and performance of 60° cone connectors and braze-on nipples with or without O-ring sealing, made of steel for tube outside diameters of 6 mm through 50 mm, inclusive, or hose sizes 5 through 51, inclusive. These connectors are for use in fluid power land 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 and ISO 1179-1. See ISO 12151-6 for related hose fitting specification.
These connectors provide full-flow connections in hydraulic systems operating to the working pressures shown in Table 1.
