Self-sealed gas pump

Automatic Shut-Off Fuel Nozzle (Exclusive for Gas Station Fuel Dispensing)

Core Differentiation
Made of aluminum alloy body + engineering plastic handle, with built-in automatic shut-off valve and filter screen for impurity prevention. It distinguishes from ordinary nozzles with "insensitive shut-off, easy dripping, no filtration", and is specially designed for gasoline and diesel dispensing in gas stations, balancing safety, efficiency and durability.

1. Performance & Specifications
- Main Material: Aluminum alloy body (lightweight, corrosion-resistant), high-strength engineering plastic handle (anti-slip, impact-resistant)
- Core Functions: Automatic shut-off when full, anti-drip, built-in filter screen for impurity filtration
- Applicable Media: Gasoline, Diesel
- Compatible Interface: Compatible with standard fuel dispenser hoses and various adapter joints
- Structural Features: With locking hook, supports continuous refueling, labor-saving operation

2. Working Principle, Scenarios & Usage
Working Principle
The nozzle integrates a vacuum-induced automatic shut-off valve: when the fuel in the tank reaches the air inlet of the nozzle, the vacuum triggers the valve core to automatically cut off the oil circuit, realizing full-tank shut-off. The built-in filter screen can filter impurities in the fuel, protecting the oil circuit of the dispenser and vehicle. The locking hook can fix the trigger for continuous refueling, reducing operation intensity.

Application Scenarios
Terminal fuel dispensing at gas station dispensers, suitable for gasoline, diesel and other vehicle fuels, meeting the standardized use requirements of various dispensers and fuel islands.

Usage
1. Installation: Connect the nozzle to the fuel dispenser hose through the standard interface to ensure no leakage;
2. Dispensing: Insert the nozzle into the vehicle tank, pull the trigger, and fix it with the locking hook for continuous refueling;
3. Shut-off: When the tank is full, the nozzle automatically shuts off the oil circuit to prevent oil spillage;
4. Maintenance： Regularly clean the built-in filter screen, check the sensitivity of the shut-off valve and seals to ensure reliable shut-off and no dripping.
