LegendFlex is a highly flexible PEX heating tube with oxygen barrier. Manufactured from a proprietary polymer formulation which dramatically increases flexibility and maintains high strength. Backed with a 30-year warranty.

LegendFlex tubing is compatible with cold expansion type fitting systems (compliant with standards ASTM F2080 & ASTM F1960).  Its strength, durability and thermal memory enables proper seal with crimp or expansion style connections.

The externally extruded EVOH oxygen 02 barrier reduces oxygen molecule permeation into the water. Compliant with standard DIN4756 (<0.1 grams/m3/day).
