Description
This 90-degree bend with plain ends provides a precise change of direction in pipework systems. Manufactured from a copper/nickel/iron alloy (CuNi10Fe1.6Mn), it offers an exceptionally high level of corrosion resistance, making it particularly suitable for pipelines carrying salt water, including saturated solutions of up to 25%.
Certified for civil and military shipbuilding and for use on drilling platforms, this fitting is ideal for saltwater cooling systems, saltwater-operated sprinkler systems, and service, pool and heating water applications.
Key Features & Benefits
- Corrosion-resistant: The copper/nickel/iron alloy withstands salt water, including saturated solutions of up to 25%.
- Certified for marine use: Approved for civil and military shipbuilding and for drilling platforms.
- Compact geometry: Requires less installation space and allows tighter fitting combinations across a wide range of applications.

(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.
