  • Manway lid gasket
    Patent number: 9944459
    Abstract: A manway lid gasket is an annular gasket that has top and bottom surfaces between the inside diameter and outside diameter of the gasket. Each of the top and bottom surfaces includes a concave, circumferential groove therein. Additionally, the gasket has a radial cut out that extends from the outside diameter face partway through the radial width of the gasket and has an annular corrugated metal insert positioned therein.
    Type: Grant
    Filed: May 19, 2015
    Date of Patent: April 17, 2018
    Assignee: Virginia Sealing Products, Inc.

  • Manway cover gasket
    Patent number: 6824140
    Abstract: The manway cover has a groove into which a gasket is adapted to be mounted. The groove has an inside diameter. The gasket has an annular metal insert having a top surface and bottom surface, and an inside edge and an outside edge and corresponding inside and outside diameters. A polymer strip is wrapped around and substantially covers the top and bottom surfaces of the metal insert. The polymer strip further has an overlap portion where the polymer strip is folded over and attached to itself, this overlap defining an inside diameter and/or outside diameter of the gasket. The inside diameter of the metal insert is no less than substantially the same as the inside diameter of the manway cover groove. The inside diameter of the gasket is less than the inside diameter of the metal insert.

  • Reduced area gaskets
    Patent number: 6682081
    Abstract: A reduced area gasket has a sealing ring around the inside perimeter of the gasket. Remaining portions of the gasket are removed or compressed so that the bolt load is focused on the sealing area when the flange is tightened. In this way, the lower bolt loads mandated by plastic piping may be met, and the required sealing may be further obtained.
