When applying the standards for sockets, difficulties arose when assembling the screw connections. In particular This was more commonly found with banjo fittings and banjo bolts.

When discussing the standards in the working group for ball bushings of the working committee for pipe fittings decided to withdraw the following standards with issue date 12.69;

DIN 7632 Teil 2

DIN 7634

DIN 7635

DIN 7636

DIN 7641

DIN 7642 Teil 2

DIN 7647 Teil 2

The withdrawal took place in 1984.


The opinion is that there is no need for these standards on the one hand, and that the application of these standards on the other no longer corresponds to the current state of the art. The LL series designation was dropped because there is no pressure assignment to a series. The dimensions of the sockets for the pipe outer diameters of 4 and 5 mm have been adjusted, and a common feature for the designation assigned. When clarifying the question of whether all pipe outer diameters are required, it was found that the pipe outer diameter knife 3 mm can be omitted. The title of the standard has been changed.
