Description
This 30° stem elbow forms part of a press-fit system built around a cupro-nickel alloy renowned for its exceptional corrosion resistance. The material is certified for civil and military shipbuilding, as well as for use on offshore drilling platforms, making it a dependable choice wherever salt water is present. The compact geometry allows tighter fitting combinations in confined spaces, while a perfected weld seam and smooth internal surface promote reliable flow and long-term system tightness. Any connection left unpressed will leak during pressure testing, giving installers a safeguard against faults reaching operation.
Key Features & Benefits
- High corrosion resistance: The copper/nickel/iron alloy withstands salt water and saturated saline solutions, making it ideal for shipbuilding and offshore use.
- Certified for demanding sectors: Approved for civil and military shipbuilding and drilling platforms, covering service, pool and heating water as well as saltwater cooling and sprinkler systems.
- Leak detection safeguard: Unpressed connections leak during the pressure test, preventing faults from reaching operation.
- Transparent protection plug: Shields the fitting from dust and dirt before installation and helps identify the application.

(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.
