Abstract
A high pressure energizable tube connector for a well comprising a tube; a first connector assembly comprising: a female profile disposed over the tube and a first ferrule disposed over the tube adjacent the female profile; a second connector assembly comprising: an inverted jam nut disposed over the tube and a second ferrule disposed over the tube adjacent the inverted jam nut, wherein the second ferrule extends along the tube in a direction opposite the first ferrule; a nipple comprising a test port, wherein the nipple is disposed over the tube between the first ferrule and the second ferrule; a primary seal formed by compressing the first ferrule into the female profile using a pressure from the test port; and a secondary seal formed by compressing the second ferrule into the inverted jam nut using the pressure from the test port.
