A PEX-Like Pipe Without the Cross-Linking Chemicals

Copper, chlorinated PVC (CPVC), and cross-linked polyethylene (PEX) all have advantages for potable water piping, but each also comes with environmental life-cycle tradeoffs.

Rigid polypropylene products are an attractive alternative because of their lower impact and cleaner chemistry. Now there’s a promising flexible alternative as well—HyperPure tubing from Legend Valve & Fitting. The product is a drop-in replacement for PEX that is recyclable, thermally fusible, and easier to manufacture because no cross-linking is required.
