The Geberit Mapress Copper T-Piece, Reduced is a press-fit branch fitting that joins three pipe runs of differing diameters at a 90° tee, forming part of the Geberit Mapress press-fit system. Pressed in seconds with a Mapress tool, it makes a secure, flame-free connection with no soldering, brazing or hot-works permit required, speeding up installation and reducing on-site risk. It is manufactured from Cu-DHP copper CW024A (EN 1412) for reliable, long-lasting performance.

Geberit press-fit security is built in: each fitting carries a pressing indicator and is designed to leak if left unpressed up to ø 54 mm, so any unpressed joint is identified during the leak test before commissioning. The pressing socket is fitted with a transparent protection plug, and uses a black CIIR seal ring up to ø 54 mm or a black EPDM seal ring above ø 54 mm.
