A/C O-ring sealant?

Yes, it fits in a groove.
The cross section is round, but the shape is irregular and not "O"
shaped, and maybe 8 inches around the perimeter. It looks like something
drawn with an Etch-a-Sketch.
Maybe I could buy cord stock and make a new seal ... no experience with this
however... not sure about sealing the ends together, and would rather not be
experimenting on this application where the only way I have to test is to
recharge the A/C system.
My thought is that, in the absence of a new replacement seal, I'd prefer to
use a sealant on the old O-ring, but don't know what kind would work best...
there are sooo many variations out there. I really don't want to have to
redo this too many more times.
Plus I have a couple of other type 44's which are leaking from the same area
of the compressor manifold, although much more slowly.
