Description
This 90° bend adaptor provides a reliable transition from a Mapress press connection to a tapered male thread, allowing pipework to change direction while joining to threaded components. Manufactured from a copper/nickel/iron (CuNiFe) alloy, it offers exceptional corrosion resistance and is suited to installations that carry salt water, including saturated solutions of up to 25%.
The fitting is certified for environments such as civil and military shipbuilding and offshore drilling platforms. Identified by its black pressing indicator, this fitting supports fast on-site material verification, while the transparent protection plug keeps the supply network free from dust and dirt until installation. A contoured seal ring ensures that any unpressed connection leaks during pressure testing, so faults are found early.
Key Features & Benefits
- Corrosion-resistant: Withstands salt water and saturated saline solutions, making it ideal for marine and shipbuilding applications.
- Suitable for different applications: Approved for civil and military shipbuilding and offshore drilling platforms.
- Secure press connection: The Mapress system delivers a fast, flame-free joint.
- Leak detection when unpressed: The contoured seal ring causes any missed connection to leak during pressure testing, preventing hidden faults.
- Fast visual identification: The black pressing indicator confirms the CuNiFe material at a glance and is easily 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.
