Description
Manufactured from the CuNi10Fe1.6Mn copper/nickel/iron alloy, this 90° press fitting with female thread is suitable for saltwater and marine environments. Its corrosion resistance makes it the fitting of choice for seawater systems, including saturated solutions of up to 25%, and it is certified for civil and military shipbuilding as well as offshore drilling platforms.
The female threaded connection allows a secure transition from the Mapress press system to threaded pipework, while the compact geometry saves space and permits tighter fitting combinations. Each fitting features the distinctive black pressing indicator for instant material identification, and the specially contoured seal ring ensures that any unpressed connection leaks during the pressure test, so installation errors are caught early. A transparent protection plug keeps dust and dirt out of the supply network before installation.
Key Features & Benefits
- Outstanding corrosion resistance: The cupro-nickel alloy withstands seawater and saturated salt solutions up to 25%, ideal for marine and offshore applications.
- Certified for shipbuilding: Approved for civil and military shipbuilding and drilling platforms, covering service, pool and heating water, saltwater cooling and saltwater-operated sprinkler systems.
- Black pressing indicator: Enables fast visual identification of the CuNiFe material, with the dimension printed on the indicator for easy verification. It is simply removed by hand after pressing.
- Compact geometry: Requires less installation space and allows tighter fitting combinations in confined plant rooms and engine 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.
