The Bend Radius of PEX Tubing

The bend radius of tubing refers to the inside curvature of the tubing. This measurement is the minimum radius that you can bend the tubing without kinking it. More flexible materials will have a smaller bend radius, allowing them to bend more before being damaged. Typically, with standard PEX tubing, you can expect it to have a bend radius of 6 times its outside diameter. Therefore, if you have 1/2" PEX tubing (which has a 5/8" outside diameter), the tubing will have a bed radius of about 3.75", making PEX tubing extremely flexible compared to other types of tubing.

You can find PEX tubing for plumbing and radiant heat at
