Hydronic Piping

How it Works

The REHAU hydronic piping system is an efficient, reliable way to transfer water from heating or cooling sources to terminal units.


Unlike alternative systems (e.g., copper), PEXa pipe will not pit, scale or corrode over time, maintaining consistent performance long after the initial installation. The clean, professional look and ease of installation of these systems have made them the top choice for many companies.


The REHAU hydronic piping system includes RAUPEX® Obarrier pipe, EVERLOC+® compression-sleeve fittings and galvanized steel support channels. With long coils of flexible PEXa piping and the immediately completed expansion/compression connection process, installation times and labor costs are reduced. Our innovative fitting, designed for no-leak security, combines with the durability of PEXa pipe to deliver exceptional reliability.
