As a counterpoint: I have had really bad luck with the Berk HFC gaskets. I opted to replace mine with the Z1 Metal HFC gaskets when the Berk ones failed. I have not had a leak due to a blow out since. The Z1 metal gaskets are durable and stand up to removal and re-installation. I would buy the Z1 metal gaskets when the Berks fail. Experience is a good teacher on this one.
