Another answer to the "Nominal bore " question: "Nominal " means name so in piping - pipe size is refered to by Nominal bore. Bore is obviously an important dimension, but if you look in your catalog like someone suggested you will find the bores are also not exactly 1/2" or 1" but have an odd exact dimesion which would be cumbersome (hard) to repeat verbally. In the US we have lumber which is Nominally called a " 2 by 4 " it is not 2" by 4" but we call it by "name " a 2 by 4
