ABSTRACT:
An end formed tube to which a molded plastic part is attached and sealed. One end of the end formed tube is rolled over to form a lip, which prevents the removal of the molded part. The rolled over lip portion creates a void in which plastic overmold from the plastic part is deposited, thereby creating a positive seal and attachment. The end of the tube in which the lip is formed is configured in a polygonal shape to provide torsional strength to the interface of the molded part and the tube.
