Abstract
Compressed wire filament(s) form a seal that seals the joint between first and second pipes of an automotive exhaust system secured by bolted together first and second flanges. The seal is initially attached to the first pipe and first flange in an intermediate assembly by an interface connection that prevents the seal from axially moving off of the first pipe prior to final assembly to the second pipe and second flange. A male projection is at the end region of the first pipe outer surface to which the seal is attached. The first flange abuts the seal at a planar seal interface. The seal has a bore with a longitudinal channel portion for initially axially engaging the projection and a transverse channel portion medially the seal bore for receiving the projection by rotation of the seal after the projection is axially displaced within the seal bore. The transverse channel portion may be tapered to wedge the projection in place to preclude accidental disengagement of the seal prior to final assembly to the mating second flange and second pipe. The joint in one embodiment articulates and in a second embodiment the joint is fixed and does not articulate. Various embodiments are disclosed.
