Corrugated stainless steel tubing (CSST) is a flexible, thin-walled metallic tubing used to supply natural gas in some residential, commercial, and industrial buildings. CSST often has a yellow or black plastic coating and is typically found inside walls and through and along floor and ceiling joists. It’s not the same as the flexible appliance connectors that attach directly to your gas appliances.

Protect against lightning

To help protect structures from potential lightning strikes, the installer of CSST and/or the owner/operator of the structure where the CSST is used should consider installing an appropriate lightning protection system pursuant to NFPA 780 or other recognized standards.

Southwest Gas doesn't provide inspection service for CSST installations. If you’re unsure whether CSST is installed in your structure, contact your builder, contractor, or a licensed plumber for an evaluation or for more information.

Class action lawsuit involving CSST

In 2002, four manufacturers of CSST settled a class action lawsuit in which it was alleged by plaintiffs, but denied by defendants, that CSST posed an unreasonable risk of gas leaks and fire due to lightning strikes.
