The Vevor automatic fuel nozzle is designed for efficient refueling with a 3/4" NPT female inlet, 15/16" spout, and up to 16 GPM flow rate. Its automatic shut-off design helps stop fueling when the tank is full to reduce leaks and spills. Built from aluminum with a PVC shell, it offers durable, rust-resistant performance for demanding use. The included 360° swivel helps protect the hose from kinking during operation. It is suitable for diesel, gasoline, and kerosene applications in stations, tankers, ships, and industrial settings.
