Description
Manufactured from a copper/nickel/iron alloy (CuNi10Fe1.6Mn), this 45° press-fit fitting is suitable for marine and industrial pipework where corrosion resistance is important. The alloy withstands salt water, including saturated solutions up to 25%, making it the preferred choice for civil and military shipbuilding, drilling platforms, saltwater cooling systems and saltwater-operated sprinkler installations.
The fitting is identified by its black pressing indicator, which allows a fast visual check of the material and displays the dimension for easy on-site identification. Its specially contoured seal ring ensures that any unpressed connection leaks during the pressure test, so installation errors are caught before the system enters service. A transparent protection plug keeps dust and dirt out until installation, while the compact geometry allows tighter fitting combinations in confined spaces.
Available in nine sizes from 15mm to 108mm, the fitting integrates seamlessly with the wider Geberit Mapress CuNiFe system of pipes and fittings.
Key Features & Benefits
- Corrosion-resistant: CuNi10Fe1.6Mn alloy performs reliably in seawater and saturated salt solutions up to 25%, ideal for marine environments.
- Certified for shipbuilding: Approved for civil and military shipbuilding and for use on drilling platforms.
- Unpressed connections detected instantly: Specially contoured seal ring ensures unpressed joints leak during pressure testing, preventing failures in service.
- Black pressing indicator: Enables visual identification of the CuNiFe material and printed dimension, removable by hand after pressing.
- Wide size range: Nine dimensions available from 15mm to 108mm (DN12 to DN100).

(1) Usable negative pressure for Geberit piping systems: The usable negative pressure is calculated on the basis of the air pressure at the place of installation minus the absolute pressure of 200 mbar. Example: 980 mbar air pressure - 200 mbar absolute pressure = 780 mbar usable negative pressure in the piping system.
