Abstract: An anti-crush ring is disclosed for insertion into hollow articles for localized reinforcement. The anti-crush ring comprises a generally annular or ring-like wall structure and at least one expansion hoop inwardly extending from the wall structure. Upon insertion of the anti-crush ring into the hollow article, the at least one expansion hoop is compressed and deformed to urge the wall structure of the anti-crush ring against an inner surface of the hollow article. Also provided is a method of reinforcing the inlet or outlet of a hollow article.

Abstract: A turbo duct is disclosed that includes a primary body having an inlet end, an outlet end, and an internal air passageway that communicates therebetween. An anti-crush ring is operably associated with at least one of the inlet and outlet ends. The inlet and outlet ends of the primary body are dimensioned to receive a cuff for connection of the turbo duct within an engine assembly. The anti-crush ring is situated on an outside surface of the turbo duct so as to form an intermediate anti-crush structure between the contact surfaces of the turbo duct and the cuff attached thereto. Also provided is a process for manufacturing the turbo duct.
