Abstract: To assemble an aftertreatment module for use in the treatment of exhaust gasses and the like, an aftertreatment brick is inserted into a sleeve opening in a sleeve and advanced toward an opposite end of the sleeve. To retain the aftertreatment brick in the sleeve, the end of the sleeve can include a stop flange and the aftertreatment brick can include a mantle flange. The stop flange and the mantle flange can abut against each other to prevent further movement of the aftertreatment brick through the sleeve. To seal against exhaust gasses leaking though the module, a gasket can be disposed between the stop flange and the mantle flange. Exterior ribs disposed around the aftertreatment brick can assist concentric alignment between the flanges and gasket.
