CSST tubing must be directly attached to supports every six feet, which of the following is the correct interval?

• A. 4 ft
• B. 5 ft
• C. 6 ft
• D. 7 ft

Answer: (C)

CSST tubing is flexible and must be securely supported to prevent movement that can stress joints. Attaching it directly to supports at six-foot intervals keeps spans short enough to avoid sag, excessive flexing, or snagging during installation, vibration, or temperature changes. This helps maintain the integrity of the gas system, so the correct interval is six feet between supports.
