Gas CSST

Both the yellow and black polyethylene-coated versions of our gas CSST is perfect for a myriad of gas applications, including but not limited to ranges, fireplaces, water heaters, dryers and gas distribution systems (residential & commercial). Although they mostly share the same characteristics, the black polyethylene coating goes one further by providing a level of lightning arc protection.

  • Lower Labor Costs (vs. Hard Pipe)
  • Flexible, Durable, Lightweight
  • Corrosion-Resistant
  • Patented 3-Step Installation (Fittings)
  • No Special Tools or Equipment Required
  • Lightning Arc Protection (Black PE-Coated)
  • Environmentally Friendly Product
