Description
The Geberit Mapress Copper Union Adaptor is designed to securely connect two copper pipes while allowing for easy disassembly, making it ideal for systems that may require maintenance or replacement of components. This union is commonly used in potable water installations, as well as in heating and cooling circuits. With a press-fit system, the union offers a fast and reliable installation process without the need for hot works, ensuring a safe and efficient connection.
Key Features
High-Quality Materials: Made from durable gunmetal (CuSn5Zn5Pb2-C) and equipped with a brass union nut, this union provides excellent corrosion resistance and durability in various applications, including potable water and heating systems.
Leak Detection: The union is designed to be leaky if unpressed for diameters up to 54 mm, making it easy to identify unpressed connections during installation, reducing the risk of leaks.
Secure Sealing: For diameters up to 54 mm, the union uses a CIIR black seal ring, while larger diameters feature an EPDM black seal ring. Additionally, the union includes a flat EPDM gasket, ensuring a reliable, leak-proof connection across all sizes.
Safe and Quick Installation: The press-fit connection eliminates the need for soldering or welding, reducing installation time, labour costs, and fire hazards. This makes the union especially suitable for renovation projects in residential areas.
Temperature Resistant: The flat EPDM gasket ensures a reliable seal for media temperatures ranging from 0°C to 100°C, making it ideal for a wide range of heating and cooling applications.
Easy Identification: The union features pressing indicators and transparent protection plugs, making it easy to distinguish product materials and avoid confusion with third-party products during installation.

(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"
