The K&S tubing is sized so that each size fits inside the next bigger size, and they are quoted in the outside diameter. This might help when looking at the Tower catalog.
The wall thickness is 1/64", so for a 3/32" inside diameter the outside is 1/8". and for a 1/8" inside diameter the outside is 5/32". The 5/32" OD tube fits into the 3/16" OD tube and so on....
If you are looking for tubing to fit over a 3/32" axle, use the 1/8" OD. For guides, if it is for a 1/8" guide shaft, use the 5/32" OD, or if it is for the 3/16" shaft (like the Parma guides) use the 7/32" OD.
I hope this helps.
