Oxygen Barrier Tubing
Oxygen barrier tubing used for closed-loop heating and cooling applications, including radiant and hydronic distribution.
It has an oxygen diffusion barrier that meets German DIN 4726/9. A polyethylene layer is extruded over the oxygen
barrier to protect from site abuse and moisture saturation.
