ABSTRACT:
The present invention pertains to a tubular connection having a stabilized center-shoulder seal. The stabilization of the center-shoulder seal is achieved using at least one run-out section of thread adjacent to the center-shoulder seal configuration of each connection member. Typically, the at least one run-out section of thread is located adjacent the side of the center-shoulder at which the connection member wall thickness is less. The run-out section of thread is typically used in combination with a run-in section of thread on the corresponding connection member.
