A tube and turbulator and method of making the same for a heat exchanger including a base, a top spaced from and opposing the base, a first side interposed between the base and the top along one side thereof, and a second side interposed between the base and the top along another side thereof. The base, top, first side and second side form a channel. The second side is triple hemmed such that ends of the base and the top are disposed within the channel. A flat turbulator may be disposed inside the tube and includes a base extending laterally and longitudinally in a strip. The flat turbulator also includes a plurality of corrugations spaced laterally along the base and extending longitudinally and generally perpendicular to the base in an alternating manner. The corrugations are rolled in a direction parallel to a longitudinal axis of the strip.
