These are the only ones I could find that fits 1/4" ID and wasn't robbing my bank. They fit the tube snugly so they won't slide around. I like how the opened sides allow to visually see if its stopping fluid flow. Because others stated one isn't stopping all flow I put 2 on my hydration bladder hoses. The clamps are bulky and have kind of sharp points at the opening corners. I'm concerned they will damage something from my hiking motion. Keeping my fingers crossed!
