The industry makes extensive—and common—use of cyro fittings for repairs on
assembled welded tubing (typically, replacing a bad thruster or valve in
situ). They are very expensive and thus used only for repair rather than
assembly.

Are they LOX rated? I believe the coupling is
wetted in use.. Moving titanium alloy metal to
metal seals and tube ends in particular seems
problematic, especially with aluminum.

I strongly suggest Cryofit couplings. I have not
used them specifically, but I have developed a
similar technology. I think Cryofit can just
sell you the fittings for whatever tube you want.Â
