Corbin hose clamps

You can get Wire Corbin clamps from Mc Master Carr
The dimension listed does not seem to propperly correlate to the OD of the hose it is supposed to clamp. I ended up getting a size larger and a size smaller than the listed size and one of the 3 worked great.

My theory as to why the work so well is they apply all the force in a very small area thus making a very tight seal at that point.

The other thing I do is use new hoses. Or put the clamp back in the exact same location if I had to remove it.

I will never use a screw clamp again.

As for the wide ones, same basic principle.
