In NFPA 54, CSST refers to which tubing material?

Explanation:
CSST stands for Corrugated Stainless Steel Tubing. It’s a flexible gas piping option used to feed natural gas or propane appliances, with a corrugated stainless steel core and often a protective jacket. NFPA 54 recognizes CSST as a specific tubing material and provides installation rules to keep it safe, including proper bonding to electrical grounding and protection from damage. The other materials listed describe different piping options: copper tubing is typically used for water and some gas applications but is not CSST; plain corrugated steel tubing is steel rather than stainless; plastic tubing is not CSST and is used in different gas systems. So the material described by CSST in NFPA 54 is Corrugated Stainless Steel Tubing.
