Description
The Geberit Mapress Copper Female Threaded Union is designed to connect copper piping systems to threaded components such as valves or fittings with a female thread. This union ensures a secure, leak-proof joint and allows for easy disassembly, making it ideal for systems requiring frequent maintenance or replacement of components. It is particularly suitable for use in potable water installations, as well as heating and cooling circuits.
Key Features
Durable Gunmetal Construction: Made from high-quality gunmetal (CuSn5Zn5Pb2-C), this union offers excellent resistance to corrosion, ensuring long-term durability in potable water, heating, and cooling systems.
Brass Union Nut: The union nut is made of brass, providing a robust and secure mechanical connection between the press-fit socket and the threaded component, ensuring a strong and reliable joint.
Leak Detection: The fitting is designed to be leaky if unpressed, allowing installers to easily identify any unpressed connections during installation, ensuring a proper and secure fit.
Reliable Seals: The CIIR black seal ring offers a secure, leak-proof connection, while the flat EPDM gasket provides additional sealing for applications involving media temperatures between 0°C and 100°C, making the union suitable for a range of thermal applications.
Press-Fit Technology: The press-fit connection eliminates the need for welding or soldering, ensuring a fast, safe, and efficient installation while reducing the risk of fire hazards, especially in sensitive areas such as residential buildings.
Clear Identification: Equipped with pressing indicators and transparent protection plugs, the union allows for easy visual confirmation of correct installation and helps to distinguish between different materials, reducing errors during installation.
Versatile Application: The Geberit Mapress Copper Female Threaded Union is suitable for surface-mounted or concealed installations, making it ideal for a wide range of plumbing applications, including new installations, renovations, and system maintenance.

(1) Usable negative pressure for Geberit piping systems: The usable negative pressure results from the air pressure at the installation site 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
(2) 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
(3) Lifetime with collector standstill: 200 h/a at 180 °C; 60 h/a at 200 °C; total 500 h/lifetime at 220 °C
(4) Use of inhibitors, corrosion-protection agents, antifreeze agents only after approval by Geberit
(5) 10 bar / 1000 kPa for MasterFix and MeplaFix
(6) Approved up to d54 mm
(7) Following Geberit approval
(8) Oil purity class in accordance with ISO 8573-1:2010E; for details on moisture and particles, see technical information "Geberit Piping Systems for Compressed Air Installations"
