  • Publication number: 20240401728
    Abstract: A gasket assembly includes a primary gasket defining an outer sealing surface and an inner sealing surface opposite the outer sealing surface; and a secondary gasket disposed radially inward of the primary gasket, the secondary gasket defining a secondary outer sealing surface and a secondary inner sealing surface, the secondary outer sealing surface engaging the outer sealing surface of the primary gasket; wherein: one of the inner sealing surface of the primary gasket and the secondary outer sealing surface of the secondary gasket defines an engagement groove; the other one of the inner sealing surface of the primary gasket and the secondary outer sealing surface of the secondary gasket defines an engagement flange; and the engagement flange engages the engagement groove to prevent the secondary gasket from sliding axially relative to the primary gasket.

  • Patent number: 12152708
    Abstract: A gasket bridge assembly includes a gasket bridge defining a first circumferential bridge end, a second circumferential bridge end opposite the first circumferential bridge end, and an arcuate body arcing between the first and second circumferential bridge ends, wherein the gasket bridge comprises: a first anti-slip feature at the first circumferential bridge end; a second anti-slip feature at the second circumferential bridge end; and a third anti-slip feature disposed between the first and second circumferential bridge ends; and a gasket assembly disposed radially inward of the gasket bridge, wherein each of the first, second, and third anti-slip features extend radially inward and dig into an outer sealing surface of the gasket assembly to prevent movement of the gasket assembly relative to the gasket bridge.
