Which component is used to change spray patterns on the vari-nozzle?

• A. HANDLE
• B. GASKET
• C. BLACK TIP
• D. BASE

Answer: (C)

The spray pattern on a vari-nozzle is changed by the end piece, the black tip. This tip contains the different openings and diffuser geometry that produce various patterns, and you adjust it—often by rotating or positioning it—to switch from a straight stream to a fog pattern (or other shapes) as needed. The handle controls the valve for flow, the gasket seals connections, and the base supports the assembly; none of those alter the spray pattern. So the black tip is the component that determines the pattern.
