ABSTRACT:
In mechanical seals adapted to perform in high temperature environments, fragile gaskets characterized by poor elasticity and conformability are used to perfect a seal between adjacent parts. Gaskets may be made of graphite, carbon, asbestos and/or fiberglass containing material. In order to perfect such a seal, gaskets with a parallelogram cross-section are used. They are expanded radially and their cross-section changed when placed between two parts during assembly.
