I dont have the tubing from 483 but I suspect it is the same as the tubing in
854/948 Go-cart (which I also dont have!).

The flexible tubing has a slightly smaller id and od compared to the hard
plastic flex tubing (which taken with flex cables as a system is one of the
more elegant systems in Technic and has been highly underused by Lego, but I
digress) but as you stated provides entirely too much resistance to be useful
as a flex tube. Personally I consider them to be two different types of tubing.
So, my personal taxonomy, which is always subject to change :)
Flexible Elememts
Flexible tubing
Soft plastic:
1. Pneumatic tubing
2. Small dia flexible tubing
3. Flexible hoses
Hard Plastic:
1. Flex tubing
2. Corrugated tubing
and the tubing from 483-854 may constitute yet another type.
