I think it was me & perhaps others. Being lazy I had never bothered to replace
the gasket in all the years I used the cartridges, but did so when I installed
the adaptor (using one of the gaskets supplied with it) and got a fine leak.
Fortunately, in addition to being lazy I am frugal & had saved all the gaskets
from over the years that came with the cartridges.
Sure enough, in addition to coming in two sizes (fat & skinny) some of the fat
ones were a bit fatter than the others. I found one that seemed to better fill
the groove of the adaptor and indeed the leak was gone.
Since you're looking for a diameter and a specific profile in a "square" O-ring
it may be hard to find on the shelf somewhere. If you send me your address I
can mail you 2 or 3 likely ones from my "collection".
