VEVOR DEF Nozzle 3/4-Inch Barb (Blue) — 11.6 GPM High-Flow Auto Shutoff with 3-Speed Trigger Lock

VEVOR 3/4-Inch Barb Diesel Exhaust Fluid (DEF) nozzle is a high-flow, auto-shutoff dispenser nozzle built for urea and industrial fluids, delivering up to 11.6 GPM with a 3-speed trigger lock and 3/4-inch (OD=19 mm) spout.

Designed for fleet operators, refueling stations, and maintenance bays, this VEVOR nozzle combines heavy-duty flow capacity with user-friendly controls. Finished in durable blue, it fits 3/4-inch barb hose connections and targets efficient transfer of DEF and similar liquids while minimizing drips. The nozzle's automatic shutoff and three-step trigger lock help control dispensing volume and reduce waste during routine fueling or fluid transfers.

How does this nozzle manage high-flow dispensing safely?

The nozzle supports a maximum flow rate of 11.6 gallons per minute while incorporating an automatic shutoff mechanism to prevent overfill. The design balances rapid delivery with safeguards so users can fill tanks quickly without constantly monitoring flow.

• Auto shutoff stops flow when target level is reached
• High-capacity 11.6 GPM rating for fast transfers
• Sturdy 3/4-inch (OD=19 mm) spout for standard connections

What control features does the 3-speed trigger lock provide?

The three-speed trigger lock gives operators fine control over flow: low, medium, and full. This is useful for metering small refills, topping off tanks, or delivering maximum flow when time is critical.

• Three trigger positions for graduated flow rates
• Lock function reduces hand fatigue during long pours
• Quick change between settings for versatile use cases

Which fluids and connections are compatible with this nozzle?

The nozzle is intended primarily for diesel exhaust fluid (urea solutions) and other compatible industrial liquids. Its 3/4-inch barb connection (19 mm OD) fits common dispensing hoses used in shops and service stations.

• Specifically suited for DEF (urea-based fluids)
• Compatible with many industrial, non-aggressive liquids
• 3/4-inch barb fitting works with standard hose inner diameters

How durable and maintainable is the VEVOR DEF nozzle?

Constructed for frequent commercial use, the nozzle features durable materials and a finish that resists everyday wear. Routine inspection and cleaning of the spout and valve components will keep it operating smoothly for extended service life.

• Robust build for repeated professional use
• Blue finish for visibility in busy environments
• Simple external parts for straightforward maintenance

Who is this for: The VEVOR 3/4-Inch Barb DEF nozzle is aimed at commercial mechanics, fleet managers, fueling stations, and industrial facilities that require a reliable, high-capacity dispenser for urea (DEF) and similar fluids. It suits users who need rapid transfers without sacrificing control or spill prevention—especially workplaces that demand durability and predictable performance from their dispensing equipment.
