A coupled threaded connection and a method for making-up a coupled threaded connection. The coupled threaded connection includes a first tubular section that includes a first external thread and a first pin nose. The first pin nose includes a first pin nose surface, a first pin seal surface, and a first pin shoulder surface. The first pin seal surface is disposed between the first pin nose surface and the first shoulder surface. The coupled threaded connection also includes a second tubular section including a second external thread and a second pin nose. The second pin nose includes a second pin nose surface, a second pin seal surface, and a second pin shoulder surface. The second pin seal surface corresponds to the first pin seal surface. The coupled threaded connection further includes a coupling including a first internal thread adapted to connect to the first external thread, a second internal thread adapted to connect to the second external thread, and an inner seal support. Upon a selected make-up of the first tubular section and the second tubular section with the coupling, the first pin nose is in an overlapping axial position with the second pin nose such that contact occurs between the first pin nose surface and the second pin shoulder surface and contact occurs between the first pin seal surface and the second pin seal surface. The contact between the first pin nose surface and the second pin shoulder acts as a positive-stop torque shoulder and the contact between the first pin seal surface and the second pin seal surface forms a seal. Upon the selected make-up, the inner seal support is in an overlapping axial position with the first and second pin noses and a selected diametrical gap exists between the inner seal support and the first and second pin noses.
