I appreciate all the input guys, but I still don't see why the need for two different sizes.
With "commercial" tubes, the threads are cut into the tube- since both have the same thread diameter, you need to start with a slightly larger diameter tube.
Oh wait I overlooked this. So the threads are actually the same size, so there is no difference in the receiver just the tube?
