Which statement describes the piping allowed on clean agent systems?

In clean agent systems, every piece of piping and its fittings must be made from materials that have been approved for use with the specific agent and the system’s pressure. The best choice says that flexible pipe, flexible nonmetallic tubing, hoses, and connectors must be of approved pressure/materials. That captures the essential requirement: compatibility and rated performance for the agent and pressure, regardless of the pipe shape or type. Flexible piping is commonly used to ease installation and routing, but it only works if it is listed or approved for the agent and pressure involved. The other options imply only a single rigid or specific material, which isn’t guaranteed to be suitable for every agent or every pressure scenario, so they don’t convey the necessary approval requirement as comprehensively.
