Geberit Mapress CuNiFe Elbow 15°
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 15° press-fit elbow is engineered for pipework systems where corrosion resistance is important, particularly those carrying seawater and saline solutions up to saturation (25%). The fitting is identified by its distinctive black pressing indicator, which allows fast visual confirmation of the material and displays the dimension for easy identification. The specially contoured seal ring ensures that any unpressed connection leaks visibly during the pressure test, so installation errors are caught before the system enters service. A transparent protection plug keeps the pressing socket free from dust and dirt until installation. Available in sizes from d28mm to d88.9mm (DN25 to DN80).
Key Features & Benefits
- Corrosion-resistant: Copper-nickel-iron alloy withstands seawater and saturated saline solutions (25%), ideal for marine and offshore environments.
- Certified for shipbuilding: Approved for civil and military shipbuilding and drilling platforms, covering service, pool and heating water, saltwater cooling and wet sprinkler systems.
- Unpressed connections are detectable: The specially contoured seal ring causes unpressed joints to leak during the pressure test.
- Black pressing indicator: Enables rapid visual identification of the CuNiFe material, with the dimension printed on the indicator.

(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.
