The DESEINOR urea refueling nozzle is equipped with a vacuum tube. When the lever is in the "open" position, the liquid flowing through the nozzle draws air into the vacuum tube via small holes on the nozzle. As long as air passes through the vacuum tube, the liquid continues to flow. Once the liquid level in the tank rises to cover the nozzle's small holes, the airflow stops, triggering the automatic shut-off mechanism.

Our stainless steel urea refueling nozzle is designed for dispensing urea or DEF (Diesel Exhaust Fluid). As a self-sealing nozzle, it automatically closes the valve only when the tank is full.
