Patent ID: 8628120

Claim:
A tubular threaded seal connector comprising: a. a coupling body, wherein the coupling body comprises: (i) a first coupling end; (ii) a second coupling end; and (iii) a J-area located between the first coupling end and the second coupling end; b. a first chamfer formed on the coupling body adjacent to the first coupling end; c. a first seal engagement portion formed on the coupling body adjacent to a first shoulder formed on a portion of the J-area, wherein the first seal engagement portion comprises: (i) a first anti-galling seal connected with the first shoulder by a first anti-galling relief portion; and (ii) a first relief groove connected with the first anti-galling seal by a first seal guide surface; d. a first threaded engagement portion formed on the coupling body between the first chamfer and the first seal engagement portion, wherein the first threaded engagement portion comprises a first imperfect first thread adjacent the first chamfer and a first imperfect last thread adjacent the first seal engagement portion; e. a second chamfer formed on the coupling body adjacent to the second coupling end; f. a second seal engagement portion formed on the coupling body adjacent to a second shoulder formed on another portion of the J-area, wherein the second seal engagement portion comprises: (i) a second anti-galling seal connected with the second shoulder by a second anti-galling relief portion; and (ii) a second relief groove connected with the second anti-galling seal by a second seal guide surface; g. a second threaded engagement portion formed on the coupling body between the second chamfer and the second seal engagement portion, wherein the second threaded engagement portion comprises a second imperfect first thread adjacent the second chamfer and a second imperfect last thread adjacent the second seal engagement portion; and wherein the threaded seal connector minimizes torque applied to tubulars being coupled to the threaded seal connector.
