Two Types of Gas Vent Caps: The gas can nozzle kit provides two types of gas tank vent caps. Metal gas can vent cap for oil tanks without vent ports at the end, you only need to drill and install them to use. Plastic gas can vent cap is used for another oil tank with an exhaust cover at the tail, and the old exhaust cover can be replaced.

Leak Proof Design: The spout tube and the spout cap are both threaded, simply tighten the cap (hexagonal) and there will be no gas leakage even during transportation. Metal gas can vent cap will not pop out due to temperature change like plastic.

Premium Material: The spout of this kit is made of soft and flexible HDPE material, which is easy to use and not easy to break. The built-in rubber ring ensures a good and tight fit with the gas can, providing you with a leak free and reassuring user experience.
