This wiper blade with integrated cleaning nozzle is a windshield maintenance component for truck cab. It sprays washer fluid directly onto glass while wiping, efficiently clearing dust, mud and oil film on the windscreen to maintain clear sight in rainy or dusty driving conditions. The rubber strip adopts graphite coating treatment for low-friction and quiet wiping, and the built-in water nozzle ensures even liquid spraying. The reinforced metal bracket fits closely to the windshield and resists deformation under vibration. Every wiper blade undergoes spray and wiping performance inspection before shipment. It replaces aged, cracked or clogged old wiper blades, and it is an essential exterior consumable part for truck cab maintenance.
