A sealing joint comprises, compressed between two parts, a stack of flexible strips separated by offset supports (); an envelop () surrounds this structure () and ensures its sealing. Under compression, the strips distort around the supports becoming very stiff for little distortion. Thus, we can rightly be wary of the consequences regarding the relief of strain on the material, notably at high temperatures.

Sealing joint with laminated internal structure for very high temperatures

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