Precision fluid and pneumatic channels

These threads have the capacity to align multiple and mixed hydraulic and pneumatic channels. This would be a nautral for 3D printing. For manufacturing, the channel ends are placed in a jig with plastic poured in. With multiple channels in a quick connections, these can be bundled for quick assembly and servicing. If your robotic hand is not working, screw on a new one.
Fine motor movements can be achieved with micro-valves on many lines. Van Cor Threads can also be valve components with a reduced number of components made of the same materials.
