BS ISO 12151-2:2003

This standard BS ISO 12151-2:2003 Connections for hydraulic fluid power and general use. Hose fittings is classified in these ICS categories:

• 23.040.70 Hoses and hose assemblies
• 23.100.40 Piping and couplings

This part of ISO 12151 specifies the general and dimensional requirements for the design and performance of hose fittings with 24° cone connector ends with O-rings, in accordance with ISO 8434-1 and ISO 8434-4. These hose fittings are made of carbon steel and are intended for use with hoses with nominal inside diameters from 5 mm through 38 mm (inclusive).

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 and pneumatic braking systems on road vehicles (as defined in the scope of ISO/TC 22), see ISO 4038, ISO 4039-1 and ISO 4039-2.

These hose fittings (see Figure 1 for a typical example) are for use in fluid power systems with hoses that meet the requirements of respective standards and in general applications with suitable hoses.
