# CSST

CSST is corrugated stainless steel tubing, a flexible gas line used inside many homes that can be damaged by lightning energy.

CSST is a flexible gas line material, often yellow or black, that runs from a manifold to gas appliances. The City of Rockwall notes it has shown itself to be vulnerable to electrical insult due to arcing that can occur during a lightning event. In arcing, heat is created, which can melt gas lines.

That is why bonding matters. See [CSST bonding](https://danielelectric.multisites.ai/glossary/csst-bonding) and [bonding](https://danielelectric.multisites.ai/glossary/bonding). A licensed plumber can confirm whether you have CSST, and a licensed electrician checks the electrical bond. See [residential electrician](https://danielelectric.multisites.ai/electrician).
