This Bialetti 6 Cup Washer/Filter Set is a genuine Bialetti spare part. Compatible with the Moka Express, Dama, Break and Mini Express, this set includes three washers and one filter. Outer diameter: 70mm. Bialetti moka pots can last a lifetime, but the one part that wears out is the gasket—the rubber ring that ensures a tight seal between the top and the bottom. This handy pack provides you with 3 replacement gaskets as well as 1 replacement filter plate to give your moka pot new life. Compatible with Bialetti aluminium 6-cup moka pots. Includes 3 replacement gaskets and 1 replacement filter. Made from white rubber and stainless steel.
