I believe it is not possible; the requirements regarding pressure and temperature for perfluorinated materials make it difficult to meet the goals of reducing weight.

I think it’s best to use metal wound gaskets, after all, the pressure is quite high

High-pressure washers, trapezoidal grooves, and similar structures must be used.

Use metal gaskets after all; safety comes first.

It’s wrapped around the silk thread; I think that’s fine.
