Description
The Geberit Mapress Male Threaded Union is designed to provide a secure connection between copper piping systems and threaded components, such as valves, pumps, or other fittings. This union allows for easy assembly and disassembly of threaded joints, making it ideal for installations where maintenance or replacement of components is required. It is suitable for use in potable water systems, as well as heating and cooling circuits.
Key Features
Durable Gunmetal Construction: Manufactured from high-quality gunmetal (CuSn5Zn5Pb2-C), this union offers excellent resistance to corrosion, ensuring long-lasting performance in demanding environments such as potable water, heating, and cooling systems.
Brass Union Nut: The union nut is made from brass, providing a strong and reliable mechanical connection between the press-fit socket and the threaded component, ensuring a secure and leak-free joint.
Leak Detection: The union is designed to be leaky if unpressed, helping installers quickly identify unpressed connections during installation, ensuring proper assembly.
High-Quality Seals: The CIIR black seal ring provides a reliable and leak-proof connection, while the flat EPDM gasket ensures a secure seal in applications with media temperatures ranging from 0°C to 100°C.
Safe and Easy Installation: The press-fit connection eliminates the need for hot works, such as welding or soldering, reducing installation time, labour costs, and the risk of fire hazards, particularly in confined or residential areas.
Easy Identification: With pressing indicators and transparent protection plugs, the union allows for easy visual confirmation of correct installation and prevents confusion with third-party products.
Versatile Application: Suitable for use in surface-mounted or concealed systems, the Geberit Mapress Male Threaded Union is ideal for both new installations and renovations in residential, industrial, or commercial plumbing systems.

(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"
