Manhole Cover is installed on the top of the tanker to prevent the inside fuel from leakage when the tanker is over rolled. With P/V vent inside to adjust the pressure. When there is pressure differences inside and outside the tanker, it will automatically inlet or exhaust air to adjust the pressure so that it can ensure the safety and environmental protection. It is suitable to transport petroleum, diesel, kerosene, and the other light fuel, etc.
