I can't say I have ever heard of a mercury seal. How about some kind of carbon seal?

If you want to seal the rotating shaft (eg passing into a vacuum) you can use magnetic oil rotary shaft seals, all the usual vacuum system makers sell them.

If you mean to pass electrical connections to the shaft, mercotac make mercury wetted slip rings.
