Abstract
In one embodiment, the wellhead system includes first and second wellhead components or members. An exemplary first wellhead member includes an internal bore and a first groove, while an exemplary second wellhead member is at least partially disposed within the internal bore such that a second groove of the second wellhead member is aligned with the first groove. The wellhead system may include a locking ring positioned within at least one of the first or second grooves, and a retaining ring at least partially disposed within the internal bore between the first and second wellhead members. Further, in one embodiment, the retaining ring is configured to selectively engage the locking ring to facilitate securing of the second wellhead member to the first wellhead member. Other embodiments of wellhead systems, devices, and methods of coupling the same are also provided.
