A part of a gasket that conducts electricity across the otherwise nonconducting gasket. Versions of the insert provide an electrical connection when installed even if the parts sealed by the gasket deflect, and do not deform under compression due to their resilient nature. The gaskets can be used in pipe joints, among other uses, resulting in a pipe joint that conducts electricity between the pipe spigot and the socket of a pipe or fixture even if a deflection event occurs.
