Representation of the parameters

The transition refers to the connection interface between the two tubes. It defines the total length of the adapter, which is equal to the sum of the tube lengths plus the length of the transition.

Details for parameter #9 ends fillet:

  • 0: no fillet
  • 1: fillet on the outside
  • 2: fillet on the inside
  • 3: fillet on both inside and outside
