Such collars are used to join, repair, or sleeve two sections of pipe—common in exhaust, air intake, or fluid systems on heavy-duty trucks and trailers. The dimensions 12x16 inches probably refer to either inner/outer diameter or length, but exact measurements could not be confirmed from public documentation. The manufacturer could not be identified; it may be a generic hardware item carried by a local supplier (Post Onsite).
