If a nonmetallic flexible connector is being used in a Category 1 health care facility to connect the manifold to the gas distribution piping, what is the maximum length (feet) permitted for the flexible connector?

If a nonmetallic flexible connector is being used in a Category 1 health care facility to connect the manifold to the gas distribution piping, what is the maximum length (feet) permitted for the flexible connector?

• A. 3 ft
• B. The use of flexible connectors is not permitted
• C. They shall be no longer than necessary
• D. 5 ft

Answer: (C)

The key idea is that nonmetallic flexible connectors should be kept as short as possible and only long enough to make a proper connection between the manifold and the gas distribution piping. There isn’t a set numerical maximum; the standard directs that the length be no longer than necessary to achieve a safe, functional connection. Using longer connectors can introduce more potential for leakage points, stress, or damage, and unnecessary length isn’t required for the installation. So the correct approach is to minimize the connector length to exactly what is needed to reach the equipment without strain or obstruction. If a longer run seems needed, consider rerouting or using a shorter connector to avoid extra length.
