Review on 🔒 OURU 6-Pack of 29mm Adjustable Stainless Steel Clamps by Ryan Gilliam

My Boat. I'm planning to replace the cheap snap clips on the fuel lines with stronger screw type clips like these. My fuel lines are 11mm in diameter as measured with my digital caliper. The smallest clamp in this kit (advertised as a 6-12mm fitting) should fit, but it doesn't. When fully screwed in, the fuel line is not even remotely compressed (see photo). I tried a second clamp of the same size and got the same result. I noticed that the small end of the worm trail hooks onto itself, which prevents it from being completely pinched. I tried to bend it inwards a bit so it wouldn't stick. While this prevented binding, the clip took on an oval shape instead of a round when screwed on. I can't use these clamps to secure the fuel lines. I ordered a different brand and type specifically for fuel lines. Hope they work.
