Geberit Mapress CuNiFe

Geberit Mapress CuNiFe is a press-fit system of pipes and fittings manufactured from a copper-nickel-iron alloy, engineered specifically for saltwater pipe fittings and marine environments. Thanks to the exceptional corrosion resistance of the cupro-nickel material, CuNiFe fittings have proven themselves in shipbuilding, offshore installations and any pipeline carrying salt water, including saturated solutions of up to 25%. If you need saltwater-resistant fittings that combine the speed of press-fit installation with the durability of copper nickel fittings, the Mapress CuNiFe range is the benchmark.

Geberit Mapress CuNiFe is certified for both civil and military shipbuilding, as well as for use on drilling platforms. These fittings for shipbuilding are approved for service water, pool water and heating water, alongside seawater cooling systems and salt water operated sprinkler systems. The compact geometry of each fitting requires less space than conventional alternatives, allowing tighter fitting combinations in confined engine rooms and ship pipework systems.

A special thermal and mechanical treatment creates a homogeneous, high-quality material structure in both pipes and fittings, while weld seams are mechanically smoothed for optimum flow behaviour and a perfectly positioned seal ring. 

Every fitting in the range carries a black pressing indicator, providing a visual check that confirms the CuNiFe material, with the dimension printed directly on the indicator. The Geberit Mapress seal ring adds a further layer of security: any unpressed connection leaks and is immediately identifiable during the pressure test, preventing problems later in operation. A protection plug keeps dust and dirt out of the supply network until installation, and the pressing indicator is removed by hand once the joint has been correctly pressed.

The range is suitable for a wide range of marine applications, from saltwater cooling pipework and seawater sprinkler pipe fittings through to offshore platform pipework and naval installations.

• Shipbuilding: certified for both civil and military shipbuilding, covering ship pipework systems for service water, pool water and heating water.
• Seawater cooling systems: saltwater cooling pipework in engine rooms and onboard plant installations.
• Salt water sprinkler systems: seawater sprinkler pipe fittings for salt water operated fire protection systems.
• Offshore and drilling platforms: offshore platform pipework carrying service, pool and heating water.
• Industry: industrial pipelines transporting salt water and other saline media.

The compact geometry of the fittings makes the system particularly effective in confined spaces such as engine rooms, where tighter fitting combinations reduce the installation footprint.

• Corrosion-resistant, built for seawater pipework: copper/nickel/iron composition provides outstanding resistance to seawater, including saturated solutions of up to 25%.
• Certified for shipbuilding: approved for civil and military shipbuilding, as well as use on drilling platforms.
• Black pressing indicator: enables fast, clear visual identification of the material, with dimensions printed on the fitting.
• Leaky if unpressed: unpressed connections are immediately identifiable during a pressure test.
• Dirt and dust protection: protection plugs protect fittings before installation.
• Compact geometry: allows tighter fitting combinations and greater flexibility in restricted spaces.
• Smooth, homogeneous surface: mechanically finished seams support optimum flow behaviour and long-term tightness.
