  • Patent number: 7434533
    Abstract: A self-sealing gasket is suitable for sealing a curved object to a surface. The gasket includes a pair of side rails and a support panel between the side rails. Respective top portions of the side rails extend above the support panel to define an object receiving channel on an upper side of the gasket. Respective bottom portions of the side rails extend below the support panel to define a deflection cavity on a lower side of the gasket. The gasket is formed of a flexible material such that when the curved object is received in the object receiving channel and the curved object and gasket are fixed to the surface, the top portions of the side rails deflect inward to seal the curved object. By virtue of material deflection, a dense material may be used for the gasket while maintaining flexibility.
