If you're tired of hard PVC hoses that crack or collapse when bent, try using silicone tubing instead. Once you use silicone tubing, you won't go back. Silicone is UV resistant; it does not age and deteriorate outdoors. The tube is very pliable and stretchy, allowing you to make tight turns and stretch it over barbs that are a little too big. This type silicone tube is very versatile - common uses are small water pumps such as PC water cooler radiators, blocks and pumps, small pumps for fountains, solar, coffeemakers, and other applications. This tube has a thick wall so it can accommodate a bend radius. U-turn without the tube collapsing when empty. And what is so awesome about silicone, is that even if it collapses, it will spring back without any creases, because the material is incredibly stretchy and resilient to damage.
