What is a Oil plug?

Oil plug, also known as oil cap or breather cap, refers to the cap used as the lid of the oil tank. Oil tanks are tanks for storing oils such as petroleum and heavy oil, and include automobile and motorcycle engines and oil tanks that store gasoline and light oil. Many of these contents are dangerous materials, so they must be strictly managed to prevent ignition and leakage. Depending on the type of oil cap, as a normal specification, it is equipped with a mechanism that releases the pressure inside the tank, so it is possible to keep the inside of the oil tank at an appropriate pressure.
