Silicone O-rings are pretty non-reactive and it's very, very nonporous, but
it will still develop a layer of residue on the outside that may affect
taste.

Note that most commercial o-rings are not silicone, because silicone rubbers
are too easy to tear. One small break on the surface will soon grow into
a complete split. You can buy silicone o-rings for some applications where
the wide temperature range is important, though.
