This part of ISO 12151 specifies the general and dimensional requirements for the design and performance of hose fittings with O-ring face seal ends in accordance with ISO 8434-3, made of carbon steel, for nominal hose inside diameters of 6,3 mm to 38 mm inclusive, in accordance with ISO 4397.
NOTE 1 Materials other than carbon steel may be supplied as agreed between the manufacturer and user.
NOTE 2 For hose fittings used in hydraulic braking systems on road vehicles (as defined in the scope of ISO/TC 22), see ISO 4038.
These hose fittings (see Figure 1 for a typical example) are for use in hydraulic fluid power systems with hose that meets the requirements of the respective hose standards and in general applications with suitable hose.
