I used these for my Silver Ultra Barrier beverage tubing. Excellent fastener, easy to install with the proper Oetiker clamp pliers, and no leaks. Does not nick or cut into the tubing and provides even clamping pressure all the way around the tubing. Much better than worm clamps and no excess metal sticks out with these type clamps.
