Automatic Fuel Nozzle 1 in NPT 19/16 in Spout - High Flow 30 GPM

In this review the focus is on a high-flow automatic diesel nozzle designed for professional fueling tasks; it is best suited to users who regularly transfer large volumes of fuel and want an automatic shut-off and robust construction. The nozzle's standout feature is its maximum flow rate of up to 30 gallons per minute, which cuts refueling time substantially, while the built-in sensor port reduces overfills and spills. This review examines how the unit performs in real-world work settings, how the swivel and hook improve handling, and whether the aluminum build lives up to expectations for longevity.

Key Features

• High flow rate: The 1 in inlet and 19/16 in spout support up to 30 GPM, letting operators refill tanks quickly during busy shifts.
• Automatic shut-off: A high sensor port automatically closes the nozzle to prevent fuel waste and limit the risk of overfilling.
• Three latching positions: Multiple latch settings let the user select a preferred flow level for better control when filling different tanks.
• 360 swivel and hook: The included 360 fuel hose swivel reduces hose stress and kinking while the spout hook allows neat, convenient storage after use.
• Durable materials: Aluminum alloy construction with a PVC outer case improves corrosion resistance and offers a long service life in outdoor environments.

Who It's For

This nozzle is aimed at fleet operators, farmers, construction crews, and marine users who need a robust, high-capacity fueling gun for frequent, large transfers of diesel. The automatic shut-off and high flow rate are valuable when speed and spill avoidance matter.

Less suitable users include occasional consumer buyers who only need small, low-pressure refills or anyone requiring a different thread or outlet size; confirm compatibility with your hose and tank fittings before purchase.

Pros & Cons

Pros

• Very high maximum flow rate that shortens fueling time for large tanks.
• Automatic sensor port and shut-off reduce overfill and fuel waste.
• 360 degree hose swivel and spout hook protect hoses and simplify storage.
• Aluminum alloy and PVC outer case offer durability for outdoor use.

Cons

• Specifically sized 1 in NPT inlet and 19/16 in spout may require adapters for some systems.
• High flow may be excessive for very small tanks or low-pressure systems.

Specifications
