In NFPA 54, CSST stands for which tubing?

Explanation:
CSST stands for Corrugated Stainless Steel Tubing, which is a flexible gas piping material used to deliver natural gas or propane to appliances. The term describes both the stainless steel composition and the corrugated, bendable construction that makes routing through tight or irregular spaces easier. It differs from copper tubing, steel tubing without stainless, and plastic tubing, which are not the recognized CSST types for NFPA 54. The correct term reflects the specific material and design intended for gas distribution in many residential applications.
