A method by which threaded sections of oil field pipe are connected to form a coupled and sealed tubular connection having proper sealing positioning at proper make-up torque. A tubular coupling has box ends and an internal mid region which forms interior shoulder regions. A seal ring is received on the mid region and mates with the end faces of the coupling shoulder and with a centrally located groove on the shoulder. The pin ends of opposing sections of pipe are received within the oppositely arranged box ends of the coupling and are made-up to a final, desired make-up position. The final position and amount of squeeze on the seal ring are controlled by utilizing the contact between the pipe pin ends and the shoulder regions of the coupling.
