Geberit Mapress CuNiFe Female Threaded 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)

Description
This T-piece joins Geberit Mapress CuNiFe pipework to threaded equipment, pressing directly onto CuNiFe pipe at both run ends and offering an Rp female thread on the branch. The copper/nickel/iron alloy (CuNi10Fe1.6Mn) delivers the high corrosion resistance that has established this system as a dependable choice for saltwater pipelines and shipbuilding.
A black pressing indicator confirms the CuNiFe material at a glance, and the specially contoured seal ring ensures that any unpressed joint leaks during pressure testing, so faults are identified before the installation enters service. A transparent protection plug keeps the pressing socket clean until connection.
The fitting suits seawater, saltwater cooling systems and wet sprinkler installations, alongside heating water, service water and process water. It is certified for civil and military shipbuilding and for use on drilling platforms.
Key Features & Benefits
- High corrosion resistance: the copper/nickel/iron alloy withstands seawater and saturated saline solutions up to 25%.
- Certified for shipbuilding: approved for civil and military shipbuilding and for drilling platforms, covering service, pool and heating water as well as saltwater cooling and sprinkler systems.
- Leak-evident pressing: the contoured Geberit Mapress seal ring causes unpressed joints to leak during pressure testing.
- Fast material check: the black pressing indicator confirms the CuNiFe alloy at a glance, while the printed pipe end shows the dimension in use.
- Space-saving geometry: the compact design allows tighter fitting combinations where installation space is restricted.
- Ready threaded branch: the female thread gives a direct transition to valves, gauges and other threaded components without extra adaptors.

(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.
