Abstract: A space utility conduit for use in space structures such as space stations. The space utility conduit includes a plurality of substantially identical interconnectable conduit segments or modules. Each module contains a plurality of utility lines for transporting a fluid or electricity or the like throughout the space structure. The modules have a lazy S-shape that enables them to be easily installed and removed from the space structure. The S-shaped module is rotatably connected to the space structure prior to it being connected to adjacently located modules. A module is also provided that allows access to the utility lines through a connector or port that is connectable to a connector located exterior to the space structure.
