Geberit Mapress CuNiFe Male Threaded Adaptor NPT
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
Engineered for demanding marine and industrial pipework, this adaptor transitions the Geberit Mapress press system to an NPT threaded connection, giving installers a fast, reliable route between pressed and threaded assemblies. Manufactured from a corrosion-resistant copper/nickel/iron alloy, it is purpose-built for saltwater service, including saturated solutions up to 25%, and carries certification for civil and military shipbuilding and offshore drilling platforms.
The fitting suits several different applications, from cooling and heating water to service and process water, seawater, wet extinguishing and sprinkler systems, compressed air and inert gases. A black pressing indicator provides immediate visual confirmation of the material, while the seal ensures that any unpressed joint leaks during pressure testing, so faults are identified before the system is commissioned.
Key Features & Benefits
- Corrosion resistance: The CuNi10Fe1.6Mn alloy withstands salt water, making it ideal for shipbuilding and marine environments.
- Leak-detecting seal: The contoured seal causes unpressed joints to leak during pressure testing, preventing faults from reaching operation.
- Black pressing indicator: Enables a fast visual check of the material and dimension, then removes by hand once pressing is complete.
- Broad application range: Certified for shipbuilding and offshore use, and suited to cooling, heating, service water, seawater, sprinkler and compressed air systems.

(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.
