Abstract

An annular gasket is formed with a tubular sleeve of flexible material. At the interior surface of one end of the sleeve a lip is directed a short distance radially inwardly. At the opposite end of the sleeve, a recess is defined in the interior sleeve surface to receive the lip when the tubular sleeve is folded back upon itself to assume a generally toroidal configuration. The gasket interiorally receives cylindrical members of one diameter when the sleeve is in its extended condition and cylindrical members of a narrower diameter when in its toroidal configuration.
