Onix Staple Up ™ is the fastest, quietest, least expensive, and most hassle free way to install radiant floor heating. Onix Tubing conducts heat through the flooring to warm your room quietly and evenly without changing your finished floor height. No need to install aluminum plates with this application. They’re simply not needed.

Unlike PEX tubing, which becomes more rigid and harder to install in cold weather, Watts Radiant’s Onix Tubing retains its superb flexibility and is great for projects like snowmelting. It’s the absolute best choice for cold weather installation, especially for tricky installations like stairways.

Onix with AlumaShield oxygen barrier weathers the extremes of any radiant heating or snowmelting application. Onix’s EPDM inner tube offers very high temperature resistance, while the Aramid reinforcing handles higher burst pressures. The EPDM cover offers abrasion, UV, and chemical resistance. Onix Tubing is sold by the coil. Use it for radiant heating, snowmelting, or supply piping to baseboard or hydro-air units. Onix Tubing is fast, easy to install, and unlike PEX, it doesn’t expand and contract in underfloor installations. Onix Tubing is tested to relevant portions of several ASTM standards and carries the UPC mark as approved by the International Association of Plumbing and Mechanical Officials (IAPMO). It carries a 25 Year Limited Warranty for radiant and hydronic applications.

What makes Onix Tubing so well suited for radiant heating and snow melting?
Crosslinked Durel EPDM is extruded into a tube and wrapped with an AlumaShield barrier and a second layer of EPDM. This composite tube is reinforced with 1000 denier aramid cord, the same incredibily tough and heat resistant material used to make fire and bullet proof shields. A final outer jacket of EPDM is applied. The result–an extremely durable, flexible tubing formed of five heat and age resistant materials, proven in tens of thousands of installations over the years.

Onix Tubing is the product that can be installed with lifelong confidence–in blazing heat and sunlight, or in Arctic frost and shadows. Used for commercial snowmelting, space heating, residential staple up and supply/return lines you'll find Onix Tubing installed in thousands of quality projects every year.
