Abstract
A gasket for sealing between the open end of a manway nozzle body of a containment vessel and an associated cover comprising a resilient annular ring member having a bail including a plurality of rigid arcuate inserts spaced about the bail that extends between radially inner and radially outer depending legs. The bail includes at least one annular upstanding chevron extending about an upper surface and at least one annular depending chevron extending about a lower surface. The inserts and bail have about the same thickness. A method includes compressing the gasket between the manway nozzle and cover, and the rigid inserts limit the compression of the gasket.
