To provide a fluid loading coupling for rotatable coupling of fluid conduits for cryogenic fluids.SOLUTION: A fluid loading coupling 1 comprises: an annular outer body 2 and an annular inner body 3, which are rotatable with respect to each other around a rotation axis; bearing rings 14, 15 therebetween; a first flange 5 connected to the annular inner body and connected to a first fluid conduit 7; and a second flange 6 connected to the annular outer body and connected to a second fluid conduit 8. The first flange comprises a first fluid conduit section 25 extending into the annular inner body parallel to the rotation axis and towards the second flange. The second flange comprises a second fluid conduit section 30 extending into the annular inner body parallel to the rotation axis and towards the first flange. The first and second fluid conduit sections define a fluid channel extending through the annular inner body. An annular seal 53 is disposed around facing ends of the first and second fluid conduit sections. The annular seal is manufactured from material that has a shrinkage rate higher than material of at least the first and second fluid conduit sections.SELECTED DRAWING: Figure 2
