    • A threaded tubular connection includes a first tube and a second tube. The first tube includes a pin member and the second tube includes a box member. A cross-sectional area of a pin critical cross-section is within approximately ± 5% of cross-sectional area of a box critical cross-section of the box member. The cross-sectional areas of each of the pin and box critical cross-sections are within approximately ± 5% of the sum of the cross-sectional areas of a box intermediate critical cross-section of the box member and a pin intermediate critical cross-section of the pin member. In a made-up state, a first seal surface on the pin engages a second seal surface on the box in a radial direction so as to form an off-center fluid tight seal that extends in an axial direction of the threaded tubular connection.
