So, my analysis of the gasket market was based on me not thinking too much. Obviously, a bit of caffeine was missing. I did a bit of research and found a list of gasket and seals manufacturers. Apparently, Freudenberg, SKF, Federal-Mogul, and Cooper are among the leading competitors in the market. In a fragmented market (there are many, many more companies) it would be wise to stake out a leading position in this market.
Bialetti was not on the list, 🙁
