Abstract

An end cap for an exhaust treatment device is disclosed. The end cap has a cylindrical housing with 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 end cap also has an integral port member extending from an annular surface of the cylindrical housing. The integral port member has a central axis aligned in the radial direction, and an exterior surface of the integral port member tangentially connects to an exterior surface of the cylindrical housing.
