Various joints within a duct assembly to allow relative movement between portions of a fluid system which are interconnected by this duct assembly are disclosed. This duct assembly is particularly suited for interconnecting a rocket fuel tank and rocket engine of a space travel vehicle. In any case, this duct assembly includes a pair of duct suctions, each of which includes a gimbal on an end thereof. The opposite ends of these two duct sections are disposed in a telescope-like arrangement with a slip joint therebetween to allow the duct sections to move at least generally axially relative to each other. This slip joint includes a pair of longitudinally spaced bushings, between which are disposed a plurality of annular seals. The bushings inhibit contain between the two duct sections by maintaining the same in spaced relation.
