Patent ID: 7815869

Claim:
A catalytic converter assembly comprising: a metallic tubular member having a first end and a second end; a first substrate disposed within the metallic tubular member: a second substrate disposed within the metallic tubular member; and a spacer axially positioned between the first substrate and the second substrate, the spacer having a cylindrical body with a first wall formed substantially perpendicular to the cylindrical body, the spacer further having a second wall formed substantially perpendicular to the cylindrical body, the first wall abutting an end of the first substrate for retaining the first substrate between the first end and the first wall for preventing movement of the first substrate, the second wall abutting an end of the second substrate for retaining the second substrate between the second end and the second wall for preventing movement of the second substrate, and at least one of the first wall and second wall extending radially outward from the cylindrical body; wherein the metallic tubular member includes an aperture centrally formed between the first end and the second end adapted to receive a sensor boss, wherein the spacer further includes a plurality of apertures formed annularly around the spacer, the aperture of the metallic tubular member being aligned with any one of the plurality of apertures during manufacture for receiving the sensor boss there through.
