What does CSST stand for in gas piping?

• A. Corrugated Stainless Steel Tubing
• B. Copper Stainless Steel Tube
• C. Carbon Steel Supply Tube
• D. Copper Soldered Steel Tube

Answer: (A)

CSST stands for Corrugated Stainless Steel Tubing. It is a flexible gas piping material used to run natural gas or propane in buildings, offering easier routing and fewer fittings than rigid pipe. The corrugated stainless steel construction lets installers bend and maneuver through spaces, and many CSST products come with a distinctive jacket (often yellow) for identification and protection; however, the jacket color can vary. This material is different from rigid carbon steel or copper piping, which is why the name CSST doesn’t describe those other options. While it adds installation convenience, CSST must be installed per manufacturer instructions and applicable codes, including proper electrical bonding to the building’s grounding system to minimize damage from electrical faults or lightning. Proper protection from physical damage and correct routing and support are also essential.
