Wet chemical discharge nozzle must be configured as what combination?

• A. Permanently marked
• B. Brass, stainless steel, or other corrosion resistant material
• C. Permanently marked and brass, stainless steel, or other corrosion resistant material
• D. None of the above

Answer: (C)

Wet chemical discharge nozzles must be both permanently marked for easy identification and built from brass, stainless steel, or another corrosion-resistant material. The permanent marking ensures inspectors and service technicians can verify the nozzle type and listing during maintenance, testing, and replacement, keeping records accurate and ensuring the right components are used. The corrosion-resistant construction is essential because the nozzle is exposed to a harsh wet chemical agent and kitchen conditions; materials like brass or stainless steel resist corrosion and maintain reliable flow and integrity over time. Relying on only one of these features could compromise either traceability or performance, so both requirements together define the proper configuration.
