An exhaust treatment device for an exhaust aftertreatment system includes a housing having a chamber for receiving exhaust gas. The housing extends between a first end and a second end and includes a first exhaust tube at the first end and a second exhaust tube at the second end. The exhaust treatment device includes a tubing fitting for the first exhaust tube at the first end having a fitting body and an annular flange at an exterior of the fitting body. The annular flange has a flange interface configured to face a mating flange of a mating tubing fitting. The tubing fitting includes a mounting bracket that extends from the fitting body configured to be attached to a bracket support. The exhaust treatment device includes a band clamp configured to be coupled to the annular flange to securely couple the annular flange to the mating flange.

A brake actuator includes a housing having a first housing component with a first annular flange and a second housing component with a second annular flange, wherein the first and second annular flanges are overlapping. A clamp ring extends circumferentially around the first and second housing components and engages the first and second annular flanges. The clamp ring includes a first end having a first tab and a second end having a second tab, wherein the second tab is spaced radially outwardly from and overlies the first tab. A deformable member couples the first and second tabs. A clamp ring, methods of manufacturing the clamp ring, and methods of assembling the brake actuator are also provided.
