Abstract:
A segmented gasket is formed from two or more gasket segments arranged end-to-end. In one embodiment, the end portions of the gasket segments overlap a predetermined amount to define a region of overlap having a thickness greater than the thickness of the individual gasket segments. An embossed region extends along the gasket segments and aligns in the region of overlap. When compressed between two flanges to be sealed, a continuous seal is formed from one gasket segment, across the region of overlap, and to the other gasket segment. In another embodiment, the gasket segments are locked together with interlocking tabs that project laterally from the end portions of the gasket segments and that are positioned outside of a joint within which the gasket segments are clamped. In a preferred embodiment the gasket segments are metal or rubber coated metal core gasket segments.
