Expandable Seal Arrangement Abstract An arrangement for radially expanding a tubular gasket includes a sliding sleeve and a compression sleeve. The sliding sleeve is formed of a thin membrane of relatively rigid material, such as nylon, hypalon or polyester. The sliding sleeve is positioned adjacent an inner surface of that portion of the tubular gasket to be expanded. The compression sleeve is disposed immediately adjacent the sliding sleeve such that the sliding sleeve serves as a slip plate for the compression sleeve when the sleeves are expanded against the inner surface of the tubular gasket. The sliding sleeve may be attached to or integrally molded into the inner surface of the tubular gasket. Another aspect of the invention involves forming the compression sleeve so as to allow it to be locked in any one of a plurality of expanded positions. The locking mechanism may be integrally formed with the compression sleeve, or may be formed as a separate element which may be molded into, or otherwise pre- attached to, the inner surface of the tubular gasket.
