Method of installing a ribbed sleeve gasket adapter

摘要

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.
