Fittings
Geberit MapressCuNiFe fittings
- Geberit MapressCuNiFe fittings and pipes made of copper/nickel/iron alloy
- Black pressing indicator indicates CuNiFe
- Dimension printed on the pressing indicator
- Non-pressed connections are leaky and immediately identifiable during a pressure test
- Protection plug prevents fittings from becoming dirty
- Particularly suitable for applications in shipbuilding or in contact with salt water

Seals
The following applications each relate to the combination of the Geberit MapressCuNiFe seal ring with the Geberit MapressCuNiFe fittings.
Geberit Mapress seal ring CIIR black
