That very much depends on the compatibility of the materials in
question. Vaseline actually frequently works, but you are correct that
silicone-based lubricants are usually better. Personally I usually don't
worry about it as the O-rings are cheap if they ever need to be
replaced, but if you put a thin (Thin! Just make the O-ring shiny! No
big globs!) coating of silicone grease on the o-rings they'll go in
easier, seal a wee bit better, and generally last longer.

It's also worth noting that some rubber-type seals will hold up better
if you try not to touch them any more than possible. Oil from your skin
reacts in such a way with some of these materials so as to cause them to
harden and crack faster than they otherwise would.
