PerformaFlex XT offers a quality insulated supply line. It's very easy: just unroll, place in trench and connect your ends and it's done, our installers love it. I also thank you for having such a variety of American made products available first priority, we appreciate your efforts.

I've sold and installed hundreds of outdoor wood boilers. I've used several brands of insulated PEX. None of them match the quality of the PerformaFlex brand manufactured by Z Supply. Jeff and his team make an outstanding product and provide excellent customer service.
