Performance of seal The structure of the three-eccentric multi-layer metal hard seal, mostly are use the sandwich of metal steel and graphite. One-layer of metal steel sheet, then one layer of graphite, and then one layer of metal steel gain. such a cycle, the specifications are different, the number of layers is also different
