flexible graphite sealing ring is not planar, as to prevent the leakage of fluid in a handling device in which a shaft (57) through a wall of the device. the sealing ring (26) has a cross section in the shape of a chevron, above and below which a profile almost complementary.this ring is made of a flexible film layers laminated graphite arranged transversely with respect to the axis of the ring. several rings (26) are put on the shaft (57) and housed inside the stuffing box (20) to fill the space between the shaft and stuffing box.the rings are oriented so that their inner surface is juxtaposed to the outer surface of the next. when a compressive force is exerted, and the interaction between these different faces different in the effect of tight fit between the shaft (57) and a housing (20), a gland to produce a seal.the asymmetric profile of each of the rings - may, in other configurations, a w profile and.
