Replacement gasket and metal filter plate for the BIALETTI Moka Express 9-cup stovetop espresso maker. This set contains the rubber sealing ring and the perforated metal filter designed to fit the 9-cup Moka Express model, restoring the original seal and ensuring stable pressure build-up and even extraction during brewing.
