Abstract
A gasket adapter for providing a sealing surface on a ribbed conduit is disclosed. The adapter is fabricated from an elastomeric material and includes a smooth, cylindrical outer surface adapter to mate with a conventional gasket employed between an opening and a conduit, or between aligned conduits. The inner surface of the adapter comprises a series of peaks and valleys which are adapted to nest with the peaks and valleys of a conduit surface. The adapter is initially fabricated with its cylindrical surface as its inside surface so that the adapter may be installed on the ribbed conduit and then inverted to provide the smooth outer sealing surface.
Claims1
A method of installing a gasket adapter on a conduit comprising the steps of providing a conduit having a surface characterized by a multiplicity of peaks and valleys, providing a gasket adapter having a smooth, cylindrical inner surface, and an outer surface having a plurality of peaks and valleys substantially complementary to the shape of the peaks and valleys of the conduit, the inside diameter of said adapter being slightly less than the outside diameter of the peaks of said conduit, axially inserting said gasket adapter on said conduit so that the smooth, cylindrical surface tightly embraces the peaks of said conduit, inverting said gasket adapter by axially and radially pulling one end of said gasket adapter until the adapter is turned insideout with the peaks of said adapter entering the valleys of said conduit and with the cylindrical valley portions of said adapter tightly embracing the peaks of said conduit.
