Geberit Mapress Stainless Steel Reducer With Plain End (18mm - 108mm)
The Geberit Mapress Stainless Steel Reducer with Plain End is a press-fit pipe reducer for joining pipework of two different diameters, forming part of the Geberit Mapress press-fit system. It delivers a secure, permanent connection in seconds with no soldering, no naked flame and no hot-works permit required, and is manufactured from corrosion-resistant CrNiMo stainless steel 1.4401 (EN 10088).

Built-in Geberit security features give confidence on every joint: a pressing indicator confirms the fitting has been pressed, while the leak-before-pressed design makes any unpressed connection immediately visible during the pressure test. The pressing socket is fitted with a transparent protection plug, and a black CIIR seal ring ensures a reliable, long-lasting seal.
