Geberit Mapress CuNiFe Female Threaded Adaptor
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 female threaded adaptor provides a reliable transition between Geberit Mapress press-fit pipework and threaded connections, manufactured from the CuNiFe copper/nickel/iron alloy known for its corrosion resistance. It is particularly suited to salt water applications, including saturated solutions of up to 25%, making it the ideal choice for civil and military shipbuilding, drilling platforms, saltwater cooling systems and saltwater-operated sprinkler installations.
Available in sizes from DN12/15 through to DN50, with female thread sizes ranging from Rp 1/2" to Rp 2", the adaptor connects press-fit pipe diameters of 15mm to 54mm. The black pressing indicator enables fast visual identification of the CuNiFe material, whilst the specially contoured seal ring ensures that unpressed connections leak during the pressure test, preventing faults later in operation.
Key Features & Benefits
- Superior corrosion resistance: CuNi10Fe1.6Mn alloy withstands salt water, including saturated solutions up to 25%.
- Certified for shipbuilding: Approved for civil and military shipbuilding and drilling platforms.
- Black pressing indicator: Enables fast visual identification of the CuNiFe material and can be removed by hand after a correct pressing operation.
- Unpressed connections detected: The specially contoured seal ring ensures leaks are immediately identifiable during the pressure test.
- Transparent protection plug: Keeps the fitting clean and protects the supply network from dust and dirt before installation.
- Comprehensive size range: Seven sizes from DN12/15 to DN50 with female threads from Rp 1/2" to Rp 2".

(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.
