The tubes touch in a longitudinal direction at points along their respective inner and outer circumferences so that precise axial alignment whether coaxial or axially offset, is achieved while preserving the necessary laminar gas flow.

Examples of the simplest geometric tube shapes employed are, for example, a square within a circle, or conversely, a circle within a square.
