I buy closed cell foam neoprene cord for hatch seals, cheap on ebay in many sizes.
Superglue sticks it well, joining cord ends to make rings etc.
You don't need it gas tight, do a reasonable job it will be OK.
A litre or two after being upside down for say 20 minutes is not your biggest problem.
Hundreds of litres becomes a problem.
