Patent ID: 7431351

Claim:
A tubular connector comprising: a first hub having an interior end, an external surface with a plurality of threads on a portion of the external surface, an exterior terminal end secured to a first tube terminal end and a first through bore having a distal counterbore and a proximal counterbore; a second hub having a second through bore, a first end and a second end, wherein the second end terminal end is secured to a second tube terminal end; a stabbing nose having a third through bore, a stabbing end and an opposed attachment end, the attachment end secured to an interior surface of the second hub proximal to the first end of the second hub; a coupling nut coaxially mounted on the second hub, wherein the coupling nut has a plurality of internal threads to threadedly engage the threads on the external surface of the first hub, wherein when the coupling nut is tightened the stabbing end of the stabbing nose is positioned in the distal counterbore of the first hub and the first end of the second hub is positioned in the proximal counterbore of the first hub, and wherein the first, second and third through bores are coaxially and linearly arrayed to create a fluid path from an interior of the first tube through an interior of the second tube; mounting means for coaxially mounting the coupling nut onto an outer surface of the second hub, the mounting means providing the coupling nut with axial positioning control; a selectably controllable heating means mounted on the coupling nut for heating a portion of the coupling nut; and a seal having a fourth through bore, wherein the seal is coaxially mounted on the first end of the second hub and is sealingly comated with the interior ends of the first hub and the second hub when the coupling nut is tightened.
