Watts RadiantPEX Hydronic Radiant and Snowmelt System

The cross-linked molecular structure of RadiantPEX offers toughness, flexibility and lasting durability. RadiantPEX is corrosion resistant and virtually maintenance free.

This radiant tube combines all of the traditional advantages of plastic pex tubing, but with an EVOH oxygen barrier. This barrier provides added protection against corrosion for the various ferrous components of a heating system.

  • Availible in 7 Diameters: 3/8 - 1-1/2 In.
  • 3/8 through 1 Watts RadiantPEX has a new outer layer and a new look. Benefits:
    • Easier to pull through joists
    • Reduces expansion noise in walls and floors
    • Protects the oxygen barrier from job-site abuse & mositure
    • Improved flexibilty
  • Three Connection System Options

Watts uses the Silane cross-linking process. Superior Silane technology enables higher burst strengths and higher anti-oxidant protection than other PEX manufacturing methods. Silane manufacturing is the most widely used process to manufacture PEX, and has been proven world-wide for over 30 years.
