Automatic Shut-Off Leak Proof Plastic Fuel Nozzle for Diesel Gasoline Kerosene Methanol Transfer Pump

DescribeThe self-sealing fuel transfer has the function of automatically closing the fuel transfer after the oil fills the container, which is an upgrade support for the metering tanker. It is especially suitable for unmanned gas stations, which can prevent oil or foam from overflowing, keep the station clean, and reduce air pollution.Designed for factories, coach yards, gas stations and home use.Auto power off when oil is complete.Easy to clean, install and maintain.Suitable for fuel, gasoline, diesel kerosene, gasoline, etc.Working PrincipleThe mouthpiece is equipped with a thin vacuum tube. When the pressure lever is in the "on" position, air is sucked in by flowing fuel transfer fluid through the small nozzle hole in the vacuum tube. As long as the air passes through the vacuum tube, the liquid will continue to flow, when the fuel tank when the liquid level rises to cover the height of the hole in the nozzle, the air stops flowing and the shut-off device fuel transfer starts automatically.
