The First to Offer a Lead-free Plumbing System

In 2009, Uponor was the first to offer a lead-free plumbing system from inlet to faucet. Today, our flexible, durable, crosslinked polyethylene (PEX) piping coupled with our proven engineered polymer (EP) and lead-free* brass fittings provide structures with a safe, clean and healthy system for transporting water.

And because Uponor PEX plumbing systems do not use torches, glues, chemicals or solvents like traditional copper and CPVC systems, it provides another win for the environment — keeping dangerous chemicals out of our plumbing systems and groundwater.
