Abstract
A threaded plug for a threaded connection includes a core having an exterior thread. At least one flank of the exterior thread forms a segment of an ellipse, wherein the segment of the ellipse extends continuously from a root of the thread to a corresponding crest of the thread. A threaded connection can be formed by combining the threaded plug with a threaded bushing having an interior thread constructed to engage with the exterior thread of the threaded plug.
