What diameter are they ?

External diameter 34 mm, internal diameter 28 mm. Hope this helps. GRB

The seals on my existing lids seem stuck fast. How do you change them?

They shouldn't be glued so likely just a bit wedged in. As long as you don't cut into the plastic of the lid you can destroy the old seal to get it out. Maybe try soaking in hot water for a while first though and it should loosen it up.

Are these suitable for use on a Sigg bottle storing fuel (Coleman fuel/white gas/Aspen 4)?

As far as I know Sigg does not make fuel bottles so I doubt they would be suitable for a bottle storing fuel. However best to phone Sigg UK and ask them.
