Ward’s WardFlex corrugated stainless-steel tubing system is an alternative to black-steel pipe and other CSST products. It is flexible, eliminates multiple service points at turns and connections, and ensures reliable flow from gas meters to appliances. It features a wide range of tubing sizes and coil lengths, double annealing for maximum flexibility, continuous run coils and easy customization options. It is helium- and vacuum-tested, and is CSA-certified for single-family, multifamily, commercial and industrial use. The WardFlex II ultra-durable piping system features a new conductive coating that disperses the electrical energy induced on tubing when an arc occurs between the CSST and another metallic system.
