pipe sleeve for brake pipes 6.00 mm, brass
The pipe sleeve is used for partial exchange of damaged brake pipes, without dismounting them completly.
In the case of repair the old brake pipe is cut and on both ends a cap screw bl-600-121f is mounted. Afterwards both ends are flanged (F-flange).
After flanging the open ends are connected by the pipe sleeve.
