What is the maximum length of a corrugated metal connector for a gas range?

• A. 2 feet
• B. 3 feet
• C. 8 feet
• D. 5 feet

Answer: (D)

Flexible corrugated metal connectors bridge the gap between the gas supply and the appliance, so their length is limited to protect safe gas delivery and mechanical integrity. The longer the connector, the more pressure is lost to friction, and the greater the chance of sagging, kinking, or pulling on fittings as the appliance shifts or is used. This can lead to poor appliance performance or leaks at the connections. The maximum allowed length for a corrugated metal connector on a gas range is five feet, which balances adequate gas flow with a reduced risk of issues. If more distance is needed, the piping should be reconfigured with rigid pipe or the appliance relocated so the connector stays within the limit, keeping the installation within code and safer to operate.
