PEX manufacturers create PEX-A grade tubing using the “Engel Method,” whereby polyethylene molecules are cross-linked in the liquid state. In addition to making it more flexible and easier to work with, this process makes it possible for users to fix any kinks in PEX that might be created during installation. Only a heat gun is required. Our new video demonstrates this process in action. Buy hePEX and AquaPEX PEX-A tubing at SupplyHouse.com.
