ISO 2974:2016

Diesel engines — 60° female cones for high-pressure fuel injection components

Standard Details

ISO 2974:2016 specifies the dimensional requirements of end-connections for high-pressure fuel injection equipment components used on diesel (compression-ignition) engines.

It is applicable to externally threaded 60° female cones (see Figures 1, 2, 5, and 6) and intended for use with high-pressure fuel injection pipe assemblies with tube outside diameters of

- up to and including 12 mm for integral female cones (see Table 1), and

- up to and including 9 mm for fabricated female cones (see Table 2).

Details of the pipe connection ends referenced in this document are shown in ISO 13296.
