Abstract
A structure and technique is disclosed to allow passing control lines, conduits or cables of all sorts through a downhole tool. The assembly provides for passage of the conduit or cable through and into the bore of the downhole tool, protected by an internal carrier. The end connections are assembled without any twisting force applied to the cable or conduit. The end connections resist torque. A jam nut on either end provides one seal, and internal seals are used against the mandrel of the downhole tool to further provide pressure isolation where the cable or conduit enters the tool body or exits. Tensile loads are passed through the tool body rather than the cable or conduit. There is complete pressure isolation between the conduit and both the tubing and the annulus.
