Abstract:
1. An end cap for an exhaust treatment device, comprising: a cylindrical housing having an axial direction, a radial direction substantially orthogonal to the axial direction, a first open end, and a second closed end opposing the first open end in the axial direction, the second closed end including a convex curved outer portion having an apex substantially aligned with a central axis aligned in the axial direction of the cylindrical housing; an integral port member extending from an annular surface of the cylindrical housing and having a central axis aligned in the radial direction and an exterior surface tangentially connected to an exterior surface of the cylindrical housing at the second closed end, wherein an outer annular surface of the integral port member distal from the first open end is located at about the same axial distance from the first open end as the apex of the convex curved outer portion.
