Description
This press adaptor union provides a secure transition from a Geberit Mapress pressing socket to a parallel male thread. Manufactured from a cupro-nickel-iron alloy and identified by its black pressing indicator, it delivers a high level of corrosion resistance that makes it particularly well suited to seawater systems, including saturated saline solutions.
The brass union nut allows the threaded joint to be broken and remade, while the copper/nickel/iron body remains fixed within the press-jointed run. The pressing socket incorporates a leak-path seal ring, so any connection left unpressed will leak clearly during the pressure test and can be identified before the system is put into service. Suitable applications include cooling and heating water with or without antifreeze, service and process water, grey and black water at a pH value of 6 or above, seawater, wet extinguishing water and sprinkler systems, compressed air, and inert gases such as nitrogen.
Key Features & Benefits
- High corrosion resistance: The CuNi10Fe1.6Mn alloy withstands seawater and saturated saline solutions.
- Leak detection: The seal ring ensures that any unpressed connection leaks during the pressure test.
- Clear material identification: The black pressing indicator confirms the CuNiFe material at a glance, reducing the risk of installation errors.
- Contamination protection: The transparent protection plug guards the pressing socket against dust and dirt until the moment of installation.

(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.
