Tested heat loss 0.67° and 1669.33 BTU per 100’ at 5 GPM*

PerformaFlex XT is our definitive answer to the solid foam pipes. It features excellent performance, flexibility, and extreme toughness. Within our 4” DUAL WALL outer casing you will find our proprietary R-Foam additive enhanced, radiant barrier covered, polyethylene foam. R-Foam has 40% higher thermal effectiveness than standard polyethylene foam. R-Foam is covered with a highly effective radiant barrier.

Z-Supply is the only underground supply manufacture to give you the R-Foam advantage. We have it manufactured for us to our specifications and laminate the radiant barrier to it ourselves.

We also have the EXTREME duty DUAL WALL outer casing manufactured to our specifications. The XT (Xtra Tough) outer casing remains very flexible with an 18” bending radius and no radiant barrier style insulated PEX product can match it for durability.

When you choose eZe Flex from Z Supply you can be sure you are getting the best value in underground supply.
