Bialetti replacement silicon seal and replacement screen to keep your favourite stovetop going for longer. These new packs from Bialetti replace the 3 ring blister packs. These silicon seals are much harder wearing than the traditional rubber seals, and Bialetti have announced that they are phasing out the 3 ring blister packs in favour of these new packs. These versions are for the stainless steel Venus model Bialetti Stovetops (please check size and metal type before purchasing).
