Column Seal Material by Application

[Soln]

Anyone have a chart that suggests column seal material by application?

I have a Naptha storage tank with internal floating roof. I'm looking for guidance in replacing the column seal material. I had a recommendation to use teflon, but I think teflon is too stiff. I appreciate if anyone is aware of a source that recommends applicable seal material for different storage products.

Thanks

In my past experiences, for EFRT the seal for column is teflon material.
