Apparatus and methods for connecting a first electrically conductive tube and a second electrically conductive tube

A method for connecting a first electrically conductive tube and a second electrically conductive tube, the method comprising:

• inserting a first electrical isolator into a flared end of the first electrically conductive tube, the first electrical isolator having a central passageway;
• positioning a second electrical isolator around the second electrically conductive tube such that the second electrical isolator engages an outer flange of the second electrically conductive tube;
• positioning a nut disposed around the second electrically conductive tube and engaging the second electrical isolator;
• and
• threading the nut onto the flared end of the first electrically conductive tube.

A method for connecting a first electrically conductive tube and a second electrically conductive tube, the method comprising:

• electrically isolating the first electrically conductive tube and the second electrically conductive tube by positioning at least a first electrical isolator between the first electrically conductive tube and the second electrically conductive tube, the first electrical isolator having a central passageway;
• positioning a first annular sealing component between the first electrical isolator and the first electrically conductive tube;
• positioning a second annular sealing component between the first electrical isolator and the second electrically conductive tube;
• and
• energizing the first annular sealing component and the second annular sealing component by axially compressing together the first electrically conductive tube and the second electrically conductive tube.
