HB7H-120 High-Flow Automatic Fuel Nozzle
A Proven 7H-Type Solution for Heavy-Duty and Commercial Refueling
The HB7H-120 Automatic Fuel Nozzle, commonly known in the industry as a 7H nozzle, is a heavy-duty, high-flow fueling solution developed for demanding commercial and industrial refueling environments. It is specifically designed to support fast, safe, and reliable fuel delivery in applications where uptime, durability, and flow performance are critical.
Across different regions of the world, this product may be referred to by various names. In North America and Australia, it is often called a high-flow diesel nozzle or truck fueling nozzle. In Europe, operators typically describe it as a commercial automatic fuel nozzle or large-bore refueling nozzle. In the Middle East, Africa, and South America, it is widely known as a fleet fueling nozzle, heavy-duty fuel gun, or industrial fuel dispensing nozzle. Despite the differences in terminology, all of these names point to the same core requirement: dependable high-capacity fueling for large vehicles and equipment.
Built for High-Volume Fueling Operations
The HB7H-120 is engineered for environments such as truck stops, bus depots, mining operations, logistics hubs, agricultural fueling points, and card-lock fleet stations. Its large 1-inch inlet and wide spout diameter allow significantly higher flow rates compared with standard passenger-vehicle nozzles, helping operators reduce refueling time and improve operational efficiency.
Whether used in attended fueling lanes or self-service commercial installations, this 7H-type nozzle delivers stable performance even under continuous, high-frequency use.
Robust Construction with Long Service Life
Designed for harsh working conditions, the HB7H-120 features a lightweight yet strong aluminum body combined with a stainless-steel main stem for enhanced corrosion resistance and structural stability. Key internal sealing components are available in durable elastomer options to ensure reliable shut-off behavior over long service intervals.
An optional stainless-steel spout tip provides extended wear resistance, making the nozzle especially suitable for fleets where rough handling and frequent coupling are common.
Advanced Safety and Control Features
Safety is a core design focus of the HB7H-120. The reinforced lever guard helps prevent misuse or forced operation, protecting both the nozzle mechanism and the vehicle. An integrated tip-over shut-off option ensures that fuel flow stops automatically if the nozzle is dropped or inverted, significantly reducing spill risk.
Precision flow control technology enables clean, accurate shut-off at the end of each fueling cycle, minimizing drips, waste, and environmental impact — an essential feature for high-volume diesel and gasoline operations.
High-Flow Performance for Commercial Demands
Unlike conventional retail nozzles, the HB7H-120 is optimized for wide flow ranges, supporting rapid fuel transfer without sacrificing control. This makes it ideal for refueling trucks, buses, construction machinery, agricultural equipment, and large stationary tanks.
The nozzle is compatible with common fuels including gasoline, diesel, fuel oil, and other petroleum-based products, making it a versatile choice for mixed-fleet fueling sites.
Flexible Configuration for Global Markets
To accommodate different installation standards worldwide, the HB7H-120 is available with multiple inlet thread options and functional variants, including standard automatic shut-off models, tip-over safety versions, and configurations with enhanced spout durability. A wide selection of color options allows easy fuel type identification or branding alignment at multi-product fueling stations.
Easy Maintenance, Lower Lifecycle Cost
The HB7H-120 is designed with serviceability in mind. Key wear components such as the spout, diaphragm assembly, main valve, and lever mechanism can be replaced individually. This modular approach reduces downtime, lowers maintenance costs, and extends the overall lifecycle of the nozzle — a major advantage for fleet operators and fueling station owners.
A Trusted Choice for Heavy-Duty Refueling Worldwide
Whether referred to as a 7H automatic nozzle, high-flow truck nozzle, fleet fueling gun, or commercial diesel nozzle, the HB7H-120 stands out as a reliable, cost-effective solution for high-capacity fuel dispensing. Its combination of flow performance, safety features, and durable construction makes it a preferred option for professional fueling operations around the globe.
