A leaking nozzle on a handheld compressed air sprayer can be fixed by changing the:

• A. Tank
• B. Nozzle Shut Off Valve
• C. Gasket
• D. Cap

Answer: (B)

The flow control at the nozzle—the nozzle shut-off valve—is what seals the spray path when you’re not actively spraying. If that valve or its seat wears or gets damaged, it won’t seal properly and liquid or air can leak out around the nozzle. Replacing the nozzle shut-off valve restores the proper seal and stops the leak right at the nozzle. Other parts aren’t implicated in a leak at the nozzle itself: the tank holds the liquid, a gasket is a seal at joints but wouldn’t fix a valve-seat leak, and the cap only seals the tank opening, not the nozzle’s flow path.
