Discharge nozzle markings must include which information?

• A. Type and Size of the Orifice and Manufacturer
• B. Manufacturer Only
• C. Color
• D. Model Number

Answer: (A)

Discharge nozzle markings provide the essential data you need to verify that the nozzle will perform correctly in the system. The key information is the type of the orifice and its size, because the flow characteristics of the nozzle depend on both the geometry (type) and the opening area (size). Knowing the orifice type tells you the discharge pattern and how the nozzle will interact with the system’s hydraulics, while the size determines the actual flow rate it can deliver under a given pressure. Including the manufacturer is important for traceability, ensuring you can source correct replacement parts and confirm compatibility with fittings and records. Relying on color alone isn’t reliable, since color codes can vary between manufacturers and aren’t a substitute for precise specifications. A model number by itself may help identify a part, but without the orifice type and size, it can’t guarantee the nozzle’s hydraulic performance or confirm compatibility with the system.
