I just want to know what makes the difference in the sizes of these nozzles.
Take for instance,this is 2-W-1 if there is another one that is 3-W-1 and another one 4-W-1 what exactly makes the size difference.
Is it the nozzle thickness,length or the hole of the nozzle.
Thanks and I look forward to hearing from you.

Was: $111.52
