TC-DC Tubing Hangers

The TC-DC is a dual coupling tubing hanger with a separate master bushing and compression type pack-off. It is utilized for dual completions with lighter tubing loads. The pack-off seal is actuated by lockdown screws. Once the master bushing is set in position, the tubing strings can be run and pulled independently. Each coupling accepts a back pressure valve profile. Due to the utilization of a separate master bushing, the TC-DC is not capable of utilizing down hole control valves or gas lift mandrels.
