Good point about the physical strength of the screwcap.

I am not sure about tefon as a sealant though. I believe the current
sealant disks (silicone I think) are carefully designed to perform
their function, and there is even research to design seling disks that
are slightly porous - in case people eventually decide that is
desirabe.
