Geberit Mapress CuNiFe Equal Tee
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
Manufactured from a high-grade copper/nickel/iron alloy (CuNi10Fe1.6Mn), this equal tee press fitting is suitable for marine and industrial pipework installations. Its corrosion resistance makes it the fitting of choice for pipelines carrying salt water, including saturated solutions of up to 25%, and it is certified for use in civil and military shipbuilding as well as on drilling platforms.
The 90-degree equal branch allows a pipeline to be divided into two lines of the same diameter, with all three connections press-fitted for a fast, flame-free installation. The black pressing indicator provides instant visual confirmation of the CuNiFe material, with the dimension printed on the indicator for easy identification. Thanks to the contoured CIIR seal ring, any unpressed connection will leak during the pressure test, so installation errors are identified immediately rather than during operation.
Each fitting is supplied with a transparent protection plug that keeps dust and dirt out before installation. Available in sizes from 15mm to 88.9mm, it suits a wide range of applications from saltwater cooling systems to wet sprinkler installations.
Key Features & Benefits
- Corrosion-resistant: The CuNi10Fe1.6Mn alloy withstands salt water, including saturated solutions of up to 25%.
- Certified for shipbuilding: Approved for civil and military shipbuilding and for use on drilling platforms, covering service, pool and heating water, saltwater cooling systems and saltwater-operated sprinkler systems.
- Black pressing indicator: Enables a fast visual check of the material and the dimension in use, and is removed by hand once pressing is complete.
- Compact design: The space-saving design allows tighter fitting combinations in confined machinery spaces.

(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.
