1. An annular seal for use in a fluid conveyance system that is subject to a high voltage event, the annular seal comprising:
a center core having a generally tubular shape, the center core having a circumferentially projected cross-section that is defined by an inner core radial surface, an outer core radial surface, and first and second core axial surfaces that are opposite one another; and first and second sidewalls each having a generally tubular shape, and each having a circumferentially projected cross-section that is defined by an inner sidewall radial surface, an outer sidewall radial surface, and first and second sidewall axial surfaces that are opposite one another; wherein:
the first sidewall is attached along one of its axial surfaces to one of the core axial surfaces, and the second sidewall is attached along one of its axial surfaces to the other of the core axial surfaces;the center core has an electrical resistance that is less than an electrical resistance of each of the first and second sidewalls; andthe annular seal is configured to seal between an inner surface of a first conduit and an outer surface of a second conduit, the first and second conduits configured to convey a fluid. |
