Geberit Mapress CuNiFe Slip Coupling
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)
- Applications: Industry, shipbuilding, salt water pipework
Description
This press-fit slip coupling joins two lengths of pipe. Its sliding socket allows the fitting to be positioned over prepared pipe ends, making it ideal for repairs, replacements and installations in confined spaces where the pipework cannot be sprung apart.
Manufactured from a CuNi10Fe1.6Mn copper/nickel/iron alloy, it delivers exceptional resistance to corrosion in salt water, including saturated saline solutions up to 25%. This makes it particularly well suited to civil and military shipbuilding, offshore drilling platforms, saltwater cooling systems and wet sprinkler systems.
The black pressing indicator gives visual confirmation of the CuNiFe material, while the contoured black CIIR seal ring ensures that any unpressed connection leaks during pressure testing. The coupling forms a permanent, reliable joint across nominal diameters from 28mm to 108mm.
Key Features & Benefits
- Superior corrosion resistance: The copper/nickel/iron alloy withstands salt water and saturated saline solutions up to 25%, ensuring a long service life in marine and offshore environments.
- Slip coupling design: The sliding socket allows the fitting to be positioned over fixed pipe ends, making it ideal for repairs and installations where the pipework cannot be separated.
- Secure press-fit connection: Geberit Mapress pressing technology provides fast, repeatable joints without hot works, reducing installation time on site.
- Leak detection when unpressed: The specially contoured black CIIR seal ring causes any unpressed joint to leak during the pressure test.

(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.
