Description
The Geberit Mapress Copper Reducing Tee is designed to create a secure and efficient connection between copper pipes of varying diameters. This fitting is ideal for potable water installations, as well as heating and cooling circuits in both residential and industrial settings. Its reducing design allows for the joining of different pipe sizes, while the press-fit technology ensures a reliable and quick installation without the need for hot works.
Key Features
High-Quality Copper Material: Made from Cu-DHP copper CW024A (EN 1412), the tee fitting ensures durability, excellent conductivity, and corrosion resistance.
Safe and Efficient Installation: The press-fit technology eliminates the need for welding or soldering, reducing fire hazards and lowering labour costs.
Leak Detection: Fittings are leaky if unpressed up to diameters of 54 mm, ensuring that any missed connections are easily detected before finalising the installation.
Reliable Sealing: Fitted with CIIR black seal rings for sizes up to 54 mm, and EPDM black seal rings for sizes over 54 mm, offering excellent sealing performance.
Universal Application: Suitable for both surface-mounted and concealed installations, the tee can be used in a variety of plumbing and heating systems.
Colour Indicators: Features transparent protection plugs and colour-coded indicator rings, making it easy to identify product materials and application ranges, preventing mix-ups with third-party products.

(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"
(9) Not for fittings with EPDM, black seal rings
