Question: what is the difference between pex pipe and pex tubing?
Answer: PEX-A is the most flexible of all PEX tubing types, has little or no coil memory and gives installer an ability to repair kinks with a heat gun. ... A lower bending radius in PEX-A (6 times the OD vs. 8 times the OD for PEX-B & C) is helpful, but offers little practical advantage in most cases.
