Hello - - try this:

  1. SelBadObjects.
  2. Invert Hide
  3. ExtractBadSrf
    You’ll see where the problem is - you can fix it up by re-trimming the relevant surfaces by hand…
  • Delete the surface that looks like a circle.
  • Untrim the conical surface.
  • ExtractSrf the outer surface and the small cylinder.
  • Untrim the hole in the outer surface
  • ExtendSrf the cone a little.
  • Use all of these surfaces to trim things back to the correct arrangement.

the left one failing when I do booleanunion, the rest booleanunion just fine

Hello - you do not say what you are unioning to what - here, if I replace the bad object in your file with my repaired version, all the ring parts can be Unioned into one.
