Abstract
A non-conductive multi-layered ringed sealing gasket for mating pipe joints along a piping assembly comprising at least two mutually joined ring-shaped bodies. The ringed sealing gasket can be comprised of a metal and the bottom gasket section is separated from the top gasket section by an inner portion that is comprised of one or more non-conductive materials that are ductile but do not flow during dynamic motion and forces associated with the motion of the pipe joints wherein at least one layer of the inner portion includes rings with toroidal wrapped fibers having voids filled with adhesives such that shear forces occurring during movement of the piping assembly are distributed predominantly in the tensile direction along the axial length of the fibers, thereby eliminating cracking of the gasket under excessive loads.
