An inner tubular wellhead member lands within the outer wellhead member, defining a seal pocket between the inner tubular wellhead member and the outer wellhead member. A seal ring is located in the seal pocket. A seal energizing ring urges the seal ring into sealing engagement with the outer wellhead member and the inner tubular wellhead member. An annular lock ring is carried with the seal energizing ring and engages the locking profile. A lock energizing ring retains the annular lock ring in engagement with the locking profile.
