As you can see, the clamps have several attributes that are important. They are made entirely of stainless steel, not the automotive variety which will use a stainless band and a plated mild steel screw mechanism that is going to rust up and make the clamp useless. The clamps are the right size. The "tail" extending out from the screw mechanism is not excessively long and not too short either. Finally, the clamps are offset and staggered in such a way that the puckered hose under the clamp creates a sort of labyrinth which will stop fluid flow in its tracks. Some people like to see all the screw heads lined up like a row of pidgeons on a power line. That looks good, but just doesn't work as well.
