When installing your PEX Plumbing system, there are likely to be a few tight turns. While PEX tubing is very flexible with a low bending radius, a plastic bend support is always helpful to assure that your tubing is and stays exactly where you want it to be. A bend support replaces the need for an elbow in many situations and is better because you do not need to cut the tubing at all. Just press your PEX tubing into the bend support and you're done.
