A radially expandable tubular connection and methods for expansion related thereto are disclosed. In an embodiment, a radially expandable tubular connection includes a radially-expandable box member. The radially-expandable box member includes an internal thread, and a non-threaded internal area including a groove providing a mechanical means for securing position of an elastomeric seal ring disposed in the groove. The radially expandable tubular connection further includes a radially-expandable pin member. The radially-expandable pin member includes an external thread for threadably engaging the internal thread. In addition, the radially-expandable pin member includes a non-threaded external seal surface carried by an elongated pin nose for engaging the elastomeric seal ring in a sealable manner. The radially expandable tubular connection further includes radial expansion of the radially expandable tubular connection when the external thread is threadably engaged within the internal thread to produce deformation to compress the elastomeric seal ring between the pin and box members to seal an annular area between the pin and box members.
