Geberit Mapress CuNiFe Elbow 90°
Technical Specification
- Manufacturer: Geberit
- Material: CuNi10Fe1.6Mn, material no. 2.1972.11
- Operating Temperature: 0°C to 100°C
- Maximum Operating Pressure: 13 bar (1300 kPa)
- Applications: Industry, shipbuilding, salt water pipework
Description
This 90° press fitting is designed for pipework carrying salt water and shipbuilding applications. Its exceptional corrosion resistance, effective even with saturated salt solutions of up to 25%, makes it the fitting of choice for civil and military shipbuilding, drilling platforms and industrial installations, including saltwater cooling systems and saltwater-operated sprinkler systems.
The black pressing indicator provides instant visual identification of the CuNiFe material. If a connection is left unpressed, the specially contoured seal ring ensures it leaks during the pressure test, so faults are identified immediately. A transparent protection plug keeps dust and dirt out of the fitting until installation.
Available in nine sizes from DN12 to DN100 (15mm to 108mm), covering a wide range of marine and industrial pipework requirements.
Key Features & Benefits
- Outstanding corrosion resistance: The CuNi10Fe1.6Mn alloy withstands seawater and saturated salt solutions of up to 25%, ideal for marine and offshore environments.
- Certified for shipbuilding: Approved for civil and military shipbuilding and for use on drilling platforms.
- Black pressing indicator: Enables fast visual identification of the CuNiFe material, removable by hand after pressing.
- Compact geometry: Space-saving design allows tighter fitting combinations in confined spaces.
- Versatile compatibility: Suitable for seawater, cooling and heating water, service and process water, wet sprinkler systems, compressed air and inert gases.

(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.
