Description
This 60° press fitting elbow is manufactured from a high-grade copper-nickel-iron alloy (CuNi10Fe1.6Mn) renowned for its exceptional resistance to corrosion, including saltwater and saturated saline solutions up to 25%. It is the trusted choice for seawater pipework, saltwater cooling systems and wet sprinkler installations, and is certified for use in civil and military shipbuilding and on drilling platforms.
Available in 42mm and 54mm diameters, the elbow allows precise 60° changes of direction within pipework. The black pressing indicator provides instant material identification, and the specially contoured seal ring ensures that any unpressed connection leaks visibly during the pressure test.
Key Features & Benefits
- Corrosion-resistant: The copper-nickel-iron alloy withstands seawater and saturated salt solutions up to 25%, making it ideal for marine and offshore pipework.
- Certified for shipbuilding: Approved for civil and military shipbuilding and drilling platforms, covering service water, cooling water and saltwater sprinkler systems.
- Unpressed connections detected: The specially contoured seal ring ensures unpressed fittings leak during pressure testing.
- Black pressing indicator: Enables fast visual identification of the CuNiFe material and is removed by hand once pressing is complete.

(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.
