Coding Systems for Identification of Fluid Conductors and Connectors
This coding system is intended to provide a convenient means of identifying the various tube, pipe, hydraulic hose type and hose fittings, not intended for use in aircraft and of transmitting technical or engineering information relating to them wherever drawings or other pictorial media may not be readily available. The code has been kept flexible to permit expansion to cover new fitting categories or styles and, if the need develops, the inclusion of additional materials. The system is also compatible with automatic data processing equipment.
It is not intended that this code should supersede established systems or means of identification. Therefore, it should be the prerogative of the user to apply the code which best satisfies his requirements.
This revision adds fitting shape codes used in new SAE J1453 and added material grades for aluminum material. The new shape codes are used by flange fittings. The new aluminum material grade is stronger and more readily available in the market than grades already specified.
