Description
This male threaded adaptor provides a secure transition between the Mapress press-fit system and BSPT tapered male threaded connections. Manufactured from a copper/nickel/iron alloy, it offers an exceptional level of corrosion resistance that makes it particularly well suited to pipelines carrying salt water, including saturated solutions of up to 25%.
The alloy is certified for civil and military shipbuilding and for use on drilling platforms, covering service water, pool and heating water, saltwater cooling systems and salt water-operated sprinkler systems. A black pressing indicator allows immediate visual identification of the CuNiFe material, while the dimension is printed on the pipe end to simplify sizing on site. The seal ring is contoured so that any unpressed connection leaks during pressure testing, allowing errors to be identified and corrected before the system enters service. A transparent protection plug keeps the socket free from dust and dirt before installation, and the compact size supports tighter-fitting combinations.
Key Features & Benefits
- Corrosion-resistant alloy: the CuNi10Fe1.6Mn copper/nickel/iron composition withstands salt water and saturated saline solutions, making it ideal for shipbuilding and marine applications.
- Black pressing indicator: enables a fast visual check to confirm the material, and can be removed by hand once pressing is complete.
- Leak detection when unpressed: the contoured seal ring causes any unpressed joint to leak during pressure testing, preventing faults from reaching the operational stage.
- Compact geometry: the space-saving design allows tighter fitting combinations and greater flexibility in confined installations.

(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.
