BS ISO 12151-4:2007

This standard BS ISO 12151-4:2007 Connections for hydraulic fluid power and general use. Hose fittings is classified in these ICS categories:

• 23.100.40 Piping and couplings
• 23.040.70 Hoses and hose assemblies

This part of ISO 12151 specifies the general and dimensional requirements for the design and performance of ISO 6149 metric stud-end hose fittings made of carbon steel, for nominal hose inside diameters of 6,3 mm through 38 mm inclusive, in accordance with ISO 4397.

NOTE 1 Other materials can be supplied as agreed between the manufacturer and user.

NOTE 2 Method of attachment of fitting to hose is optional, for example, permanent, field-attachable, push-on, beaded, etc. Also included is a 90° elbow hose fitting suitable for hose connections made with or without hose clamps in relatively low-pressure applications.

NOTE 3 See ISO 4038 and ISO 4039 for hose fittings used in hydraulic and pneumatic braking systems on road vehicles (as defined in the scope of ISO/TC 22).

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 hoses.
