McMaster or Grainger and if they don't have it, contact Loctite or Permatex, they both sell/sold custom o-ring kits. Yards of butyl tubing with a special adhesive and cutting jig, so you can make up any o-ring you want.
You can also do a failry good job by taking a foot or two of black plastic tubing, or black vacuum tubing, or clear tygon tubing, forming it into a circle, splicing the ends on a 45-degree diagonal (not just butting them up) and then using a good glue to seal them. O-ring glue, or one of the crazy-glue variants that says it is OK for use on flexible surfaces.
If you do it that way, buy enough to make 2-3 and practice first.
