PEX Tubing with Oxygen Barrier
Everhot Oxygen Barrier PEX Tubing is manufactured to ASTM F876/F877 standards and is pressure rated 100psi at 180F.
Oxygen Barrier PEX can be used for a large number of radiant heating applications, such as radiant floor heating, snow melt systems, baseboard and radiator systems and for boiler supply and return lines.
Oxygen Barrier PEX features an Oxygen Diffusion Barrier per DIN 4726 standard, which helps to prevent corrosion of cast iron parts in a heating system (circulators, radiators, boiler heating elements, etc.)
Available in a variety of sizes and lengths.

Additional information:
Under normal design conditions, the size of tubing is determined by heat load requirements and the application type, and is specified by the engineer who designs the radiant heating system.
1/2" PEX is the most common one and is used for majority of radiant heating applications, such as subfloor installations, concrete slabs, sandwich type installations and engineered floors.
3/4" PEX is commonly used for snow melt systems, since they require a higher flow rate than radiant heating systems. It is also very common for baseboard and radiator heating.
1" PEX is generally used for supply and return lines to the boiler or the manifold. This tubing is also popular for outdoor wood furnace installation. It can also be used to carry a supply and return water for a radiant heat manifold.
3/8" size is used in non-structural slabs (under tile) for residential applications - bathrooms, kitchens, etc. It is a preferred size for smaller areas due to it's flexibility.
5/8" PEX sometimes replaces 1/2" tubing when project calls for higher heat loads or flow rates. It can also substitute 3/4" PEX in applications that require more flexibility and less flow (such as small snow melt systems).
