Abstract
The control line exiting coupling provides radial penetration of a control line through a tubing hanger wall, with a back seat for sealing should internal pressure create a packing leak on the penetrator. The back seat further prevents withdrawal of the device through the packing and provides for withdrawing the control line tubing so the hanger may be removed from the wellhead without shearing off the control line tubing.
