A tubular assembly comprising a hollow elongated tube 11 having an internal cross section with an inside surface, a proximal end and a distal end defining a bore around a longitudinal axis and a part 12 mounted within the bore so that it is at least partially within the tube 11, the part having been thermally treated to expand and engage the inside surface of the tube and thereby from a fluid tight seal. A method and apparatus for making such a tubular assembly is also disclosed. <IMAGE> |
