Origo Stove parts

[IslandMac]

We're trying to find a replacement gasket (disk) for a one burner Origo stove. On a ancient post somewhere, I saw that they were asking about $5 for this little piece of rubber. Now I've just found one source for this piece, and it is currently $17.99. Seems kind of high to me. Does anyone know a cheaper source? (The Captain made his own version, but it was apparently not the correct type of rubber, and did not last.) Thanks for any help!

All that gasket does is keep thee alcohol in the fuel canister from evaporating while the stove is not in use. You can make one for a lot less than the process you quoted.

I made one out of duct tape after forgetting to remove the disk prior to boiling a pot of water.

Aside from a handful of materials I can think of to make something suitable - perhaps the easiest is to cut a piece of a foam rubber mouse pad.
