That type of connection is sometimes called a conflat flange, they need
fairly high clamping forces to work but are also fine for high pressures
and cryogen when designed/made properly.

I don't know about He, but some high vacuum systems use fittings with a
couple of machined sharp bumps in a ring on each side, with a flat copper
disc sealed in between with the sharp bumps pressing into the malleable
copper.
One use per "gasket" but they seem to work well, and copper recycles
fine...

Wouldn't designing your system with stainless steel O rings eliminate
the issue? We use them on our oxidizer flanges including cryogenic and
they seem to work quite well.
