PEX Tubing with Oxygen Barrier also known as EVOH (Ethylene Vinyl Alcohol) polymer is constructed for use with radiant floor heating, ice melting, and hydronic heating applications. The oxygen barrier is designed to restrict oxygen from entering the pipe, and further resulting in corrosion of corrosion sensitive materials. Oxygen Barrier PEX Tubing is flexible, lightweight, durable, and can withstand heat of up to 180 degrees Fahrenheit.
This PEX tubing meets the standards set by ASTM F867/877, CSA B137.5, DIN 4726 and is certified by the NSF for radiant floor heating applications. Pressure ratings for this tubing are as follows: 79PSI @ 200F, 100PSI @ 180F, 160PSI @ 73F.
