Which accessory on the jetter hose protects the nozzle and prevents it from turning in the hole?

• A. Hose Guard
• B. Extension With Fins
• C. Shield Cap
• D. Nozzle Keeper

Answer: (B)

In jetting, keeping the nozzle oriented and protected as it travels through the pipe is essential. An extension with fins attaches just ahead of the nozzle and adds stabilizing fins that interact with the flow to create drag, helping to prevent the nozzle from spinning or turning in the hole. That stabilization keeps the cleaning action consistent and reduces wear on the nozzle by limiting unnecessary rotation. The fins also provide a protective buffer, distributing contact forces and shielding the nozzle from rough spots or debris inside the pipe. Other accessories serve different protective or securing roles—protecting the nozzle tip, securing the nozzle in place, or guarding the hose—but they don’t offer the same anti-rotation stabilization as an extension with fins. This makes the extension with fins the best choice for preventing nozzle rotation and protecting it during jetting.
