I have a love/hate relationship with Oetiker "Stepless" RE-USABLE screw clamps. (NOT the cheaper and more-common single-use "ear" clamps.) IF you can get them to fit your application, they're WONDERFUL. Thin, for high contact pressure (PSI) without squeezing the hose so bad it cold-flows. There's a trademark "Green" coil spring on the tension screw for constant torque in varying temperature. And "shielded" in that there's no worm-gear openings for the hose to cold-flow through. But where I was using them--primarily on silicone hump-hoses, the wall thickness variation of the hose was so great we needed to stock several sizes of Oetiker clamps to do what should have been identical jobs. In other words, the clamp range of the Oetiker design was so limited that it made assembly difficult. (Or, conversely, the uniformity of the hump-hoses we used was so poor that they were often incompatible with the clamps we were required to use.) Oetiker is "Global", headquartered in Switzerland, manufacturing all over Europe, China, and "North America" (Canada, USA, Mexico.)

I really like the SHIELDED Breeze clamps, especially the "Constant Torque" version with the stack of Belleville washers on the tension screw. The "Constant Torque" clamps are rather huge, and kinda unsightly. But they work VERY well, and they have the usual worm-gear clamp range of sizing. Being shielded, the hose doesn't cold-flow through the clamp.

Unshielded worm-gear clamps are an abomination in any size. Smaller sizes, like fuel hoses, can be clamped with inexpensive "fuel injection" clamps in 1/4", 5/16, and 3/8 sizes. I get mine from Summit.
