Casing Hanger
The subassembly of a wellhead that supports the casing string when it is run into the wellbore. The casing hanger provides a means of ensuring that the string is correctly located and generally incorporates a sealing device or system to isolate the casing annulus from upper wellhead components.
Pack-off Bushing
The pack-off bushing lands on the casing hanger to suspend and seal the intermediate casing string(s). The inner seal on the bushing is energized by plastic packing. This seal can be reenergized, if necessary, throughout the life of the well. The outer seal is radially energized.
