Description
This reducing tee forms a 90° branch connection between pipe runs of differing diameters within a press-fit system. Manufactured from copper/nickel/iron alloy, it delivers the exceptional corrosion resistance required for pipelines carrying salt water, including saturated solutions of up to 25%.
The fitting is certified for civil and military shipbuilding and for use on drilling platforms, covering service water, pool and heating water, saltwater cooling systems and salt water-operated sprinkler systems. Identified by its black pressing indicator, the fitting allows the material to be verified at a glance, while the printed dimension on the pipe end aids correct selection on site. The transparent protection plug shields the pressing socket from dust and dirt until installation, and the CIIR seal ring is contoured so that any unpressed connection leaks during the pressure test, revealing installation errors before the system enters service. The compact geometry keeps space requirements low and permits tighter fitting combinations.
Key Features & Benefits
- Corrosion-resistant alloy: The copper/nickel/iron composition withstands salt water and saturated saline solutions, making it ideal for shipbuilding and marine use.
- Certified for marine service: Approved for civil and military shipbuilding and drilling platforms, giving confidence for critical seawater applications.
- Secure press-fit connection: The seal ring is designed so unpressed joints leak during testing, allowing installation faults to be identified and corrected early.
- Black pressing indicator: Enables fast visual confirmation of the material and can be removed by hand once the joint has been correctly pressed.
- Compact geometry: Reduces installation space and supports tighter fitting arrangements in confined plant and vessel layouts.
- Smooth internal surface: Precisely finished weld seams promote optimum flow behaviour and reliable, long-term tightness.

(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.
