Abstract:
An exhaust processor comprisingan exhaust processor body including an outer shell and a substrate positioned to lie within the outer shell and in spaced-apart relation to a first axially outer edge of the outer shell to define a first end cap region located within the outer shell and bounded by a cylindrical inner surface of the outer shell anda first end cap including an annular body portion formed to include an outer rim defining an axially outer opening, an inner rim defining an axially inner opening, and an exhaust product conductor passageway extending therebetween to communicate with a first end face of the substrate, an annular flange support including an annular rounded end and a cylindrical standoff positioned to lie between and interconnect the annular rounded end and the inner rim, and a deformable annular flange coupled to the annular rounded end and arranged to surround the cylindrical standoff to form an annular channel lying therebetween and opening axially outwardly away from the substrate, the deformable annular flange being movable relative to the annular rounded end from an expanded position wherein the outer diameter of the deformable annular flange is greater tan the inner diameter of the cylindrical inner surface of the outer shell to a deformed position wherein the annular rounded end is positioned to lie in the first end cap region and an outer mating surface of the deformable annular flange mates with the cylindrical inner surface of the outer shell to mount an axially inner portion of the first end cap in the first end cap region formed within the outer shell.
