Previously, you had to disconnect the water adapter and the hose with R 1/4" thread and then put the usual blue adapter,
12029, then, for example, a suitable paint brush. Now it is faster and easier by just screwing this adapter directly on the R 1/4" screw on, for example, the water shaft without loosening the hose or existing water adapter.
On our regular telescopic shafts without a hose, you use the corresponding art.no
12029 which does not have a brass nut inside as you do not have to disconnect a water adapter.
NOTE: The adapter is
not intended to lead the water on from e.g. water telescopic handle but only intended as a faster and easier change to another tool, such as a suitable paint brush. The water should of course be turned off when you put on this adapter and are going to paint with, for example, a brush.
