PureFlow Press


PureFlow Press

Known for forward-​thinking system solutions, Viega offers complete plumbing systems for potable water. By combining the highest-​rated PEX tubing on the market (according to industry standards), the revolutionary Viega ManaBloc and Viega PureFlow Press manifolds in high-​performance polymer, Viega PureFlow System works together to save time, labor and cost. The first press system for the PEX market, Viega PureFlow Press fittings improve consistency and reduce installation errors with factory-​attached sleeves.

Available in high-​performance polymer and Viega Zero Lead bronze, Viega PureFlow Press fittings are ideal for residential and commercial jobs. Viega also offers fittings for easy copper-​to-​PEX transitions, and system-​matched tools and jaws make installation easy and consistent. Viega PureFlow also includes the versatile Viega FostaPEX multilayered tubing for plumbing and radiant heating applications, designed to be both rigid and highly flexible while holding its shape for plumbing and radiant heating applications.
