Bushing and flanges

Bushing insulator There is bushing for conduits between 16 and
Bushing insulators are used in concrete casting, 50 mm thick. When bushing is used, the conduit’s
for example when moving from the ceiling to the angle of departure is either 45° or 90°. The pre-
partition walls. The bushing is fastened by nailing bent conduit elbows speed up installation
it to the mould. When the mould is disassembled, significantly.
the nails come loose with the mould. The casting
protector included with the bushing prevents the
concrete from entering the conduit.

Wall bushing
Wall bushing AS20 is used in the fastening of Ø 20
piping materials to the mould during concrete
casting. Once the mould has been disassembled,
an installation conduit of the same size can be
attached to the extension bushing, and pipe
laying can be continued.
