Stovetop coffee machines

[AuldAlliance]

Does anyone know where I can get replacement rubber gaskets for a Bialetti stovetop coffee pot? DH left ours on the cooker for a bit too long and the rubber has died.
(At least it didn't explode, like it did last time he played the same trick. We kept finding burnt coffee grounds in the strangest places for months afterwards.)
TIA

Have you googled it.

Try the Algerian coffee shop on Old Compton Street in Soho

I have googled it, but there were so many hits for that make of coffee pot, I was left reeling.
Thanks for the tip, Chocadora.
