ABSTRACT:
An adaptor for connecting tubular members in an exhaust system. The adaptor comprises a tube having opposite ends that are curled outwardly in a generally circular configuration. The curled ends of the adaptor are press fitted within the ends of the tubular members of the exhaust system and each curled end is disposed adjacent an internal shoulder in the respective tubular member. Exhaust gases passing through the adaptor will heat the adaptor causing it to expand axially to bring the curled ends into firm contact with the respective shoulders, and the outer surfaces of the curled ends will flatten against the walls of the respective tubular members to provide a tight seal between the adaptor and the tubular members.
