Highly flexible PEX heating tube

LegendFlex™ Highly flexible PEX heating tube with oxygen barrier is manufactured from a proprietary polymer formulation which dramatically increases flexibility and maintains high strength.

Available in 3/8in, 1/2in, 5/8in, 3/4in and 1in tube sizes. LegendFlex™ delivers greater performance and flexibility than standard PEX. We are so confident in its performance we back it with a 30-year warranty.

LegendFlex™ is extremely flexible and very difficult to kink. In the unlikely event one should occur, simply repair it with a heat gun. No need to cut and use a coupling or replace the tubing.

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