Gates polymeric (shrinkwrap) hose clamps

I have not used them. But considered them. They are pretty expensive. And not reusable.

I use ABA clamps. There are other clamps just like them with different brand names. They have a smooth ID without thread holes for hose rubber to squeeze through. Also, the edges are slightly rolled up so as not to dig into the hose.
