Geberit Mapress CuNiFe Flange PN10/16
Technical Specification
- Manufacturer: Geberit
- Material: CuNi10Fe1.6Mn, material no. 2.1972.11
- Operating Temperature: 0°C to 100°C
- Maximum Operating Pressure: 10/16 bar

Description
This press-fit flange provides a fast, dependable connection between pipework and flanged equipment. The alloy delivers outstanding resistance to corrosion, making it particularly well suited to pipelines carrying seawater, including saturated salt solutions of up to 25%, as well as saltwater cooling and sprinkler systems.
A black pressing indicator allows the material to be identified at a glance, while the contoured seal ring ensures that any unpressed connection leaks during the pressure test and is spotted before the system enters service. A transparent protection plug keeps the socket free from dust and dirt until installation. Certified for civil and military shipbuilding and for use on offshore drilling platforms, it carries a PN 10/16 rating to Design B1 (raised sealing strip with standard sealing strip) in accordance with EN 1092-3.
Key Features & Benefits
- High corrosion resistance: The copper-nickel-iron alloy withstands seawater and saturated salt solutions of up to 25%.
- Rapid press-fit installation: The pressing socket connects using Geberit pressing technology, avoiding welding and soldering to save time on site.
- Built-in leak detection: The contoured seal ring means any unpressed joint leaks during pressure testing.
- Clear material identification: The black pressing indicator confirms the CuNiFe material at a glance and can be removed by hand once pressing is complete.
- Broad application range: Approved for seawater, heating and cooling water, service water, wet sprinkler systems, compressed air and inert gases, covering a wide range of industrial and marine applications.
- Certified for demanding sectors: Suitable for civil and military shipbuilding and offshore drilling platforms.
-
Standardised flange design: Manufactured to Design B1 (raised sealing strip with standard sealing strip) in accordance with EN 1092-3 with a PN 10/16 rating.

(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.
