The Groz Manual DEF Control Nozzle safely and efficiently dispenses DEF, urea, windshield fluids, and water-based media. This nozzle has a manual control via a trigger with a trigger guard as well as a continuous flow switch that enables unattended dispensing. It is made from resilient nylon, stainless steel internal parts, and a Viton seal, making it strong and durable. The spout is 4 23/32” (120 mm) long and has a nozzle hanger. The design of the pump itself maintains minimal back pressure while manually pumping and has an anti-slip protection that prevents mishaps during delivery.
