Description
Designed for passing pipework safely through bulkheads and decks, this fitting combines a corrosion-resistant cupro-nickel body with a coated steel protective tube that is welded directly into the structure. The two plain ends allow straightforward integration into the wider Geberit Mapress CuNiFe press-fit system, making it a dependable choice for marine and offshore installations.
Manufactured from the CuNi10Fe1.6Mn alloy, it offers a high level of corrosion resistance, performing reliably in contact with salt water, including saturated solutions of up to 25%. The Geberit Mapress CuNiFe system is certified for civil and military shipbuilding and for use on drilling platforms, covering service, pool and heating water, saltwater cooling systems and saltwater-operated sprinkler systems. Available in DN65 and DN80, this fitting is supplied ready for welding, providing a clean penetration point that maintains the integrity of both the pipework and the surrounding structure.

(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.
