Laufen 40mm Dual Flush Push Button — Chrome
The Laufen 40mm Dual Flush Push Button is a precision-engineered replacement mechanical flush button designed specifically for Laufen ceramic WC cistern lids featuring a 40mm hole diameter. Finished in durable polished chrome, it features a split-button design for full and eco water-saving flushing.

Installation & Measurement Guide
Laufen cistern lids were produced with either a 40mm or 50mm button hole. Please measure the diameter of the hole in your cistern lid prior to ordering to ensure this 40mm version matches your cistern. This button connects mechanically to compatible drop-in valves such as the Laufen OV302 / OV203C; it is not compatible with pneumatic air-hose flush systems.
