Abstract
The seal can be used at high temperature. It is composed of a central flexible graphite core (10) maintained in its shape by two metal cups (12) that do not touch. It is all surrounded by a tight sheath (15) enabling the flexible core (10) to be maintained in a neutral atmosphere such as a partial vacuum or a neutral gas.
