I use them for a column to keg gasket.

There is such a small surface area in contact with the liquid it's not worth worrying about.
Silicone has good ethanol resistance and it's OK for ethyl acetate and butanol etc, but not recommended for a prolonged soak.
I used to wrap them in teflon tape, but now I don't bother.
I've used the same gasket now for about 9 months and it's as good as. :handgestures-thumbupleft:
