Geberit Mapress CuNiFe Stem Elbow 45°
Technical Specification
- Manufacturer: Geberit
- Material: CuNi10Fe1.6Mn, material no. 2.1972.11
- Operating Temperature: 0°C to 100°C
- Maximum Operating Pressure: 13 bar (1300 kPa)

Description
This 45° stem elbow forms part of the Geberit Mapress copper/nickel/iron press-fitting system. Manufactured from a cupro-nickel alloy and identified by its distinctive black pressing indicator, it delivers outstanding resistance to corrosion, making it well suited to pipelines carrying salt water, including saturated solutions of up to 25%.
The range is certified for use in civil and military shipbuilding, on drilling platforms and within saltwater cooling systems. The compact geometry keeps space requirements to a minimum and permits tighter fitting combinations, while the black CIIR seal ring provides an added layer of safety by revealing any unpressed connection during pressure testing.
Key Features & Benefits
- Exceptional corrosion resistance: The copper/nickel/iron alloy withstands salt water and saturated saline solutions of up to 25%, ideal for marine and offshore environments.
- Leak detection when unpressed: The seal ring causes any unpressed joint to leak during the pressure test, preventing faults in later operation.
- Compact 45° geometry: The space-saving design allows tighter fitting arrangements and greater flexibility in confined pipework layouts.
- Certified for shipbuilding: The range is approved for civil and military shipbuilding, drilling platforms, and saltwater cooling and sprinkler systems.

(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.
