Can a hose clamp be over-tightened?

Then there the combined heat shrink quick disconnect clamp that Ford used in some vehicles https://www.youtube.com/watch?v=_SvH93cmO-M

Thats why Ford use shear clamps.

That's why Ford use shear clamps.

Or is it just so we have to but a new hose clamp from them each time we change a hose and Ford's parts revenue is increased :-) But yes it prevents over-tightening.

No, its a normal clamp once you remove the sheared cap..

Not sure if this is correct or not, but I was once told to tighten a hose clamp until the clamp is virtually flush with the thickness of the hose. So the hose and tightened clamp will be same outside diameter.

I usually follow this rule and have done for years without issue.
