Abstract

A system formed to provide sealed passage through the wellhead for cables, lines, tubes or the like for down-hole applications. A unitary or split/wrap around hanger, packer or other apparatus having a main seal is formed to receive and provide sealed passage through of power and control cables, lines, conduits, or other threaded components having various configurations and applications. A bowl cap, tubing adapter or other surface component with adapters is formed to allow sealed pass-through utilizing a compression seal. A tubing encapsulated wire for pass-through for power cables or the like as well as a compression fitting with right angle connector is configured to provide a seal at the tubing adapter or the like, as well as a two-piece interlocking F.A.N. cover plate utilizing insertable inner plates to provide various cable penetration and other passage layouts, pressure ratings, and other specifications.
