What Is an Oil Drain Plug?
An oil drain plug, also known as an oil cap or breather cap, is a cap used as a lid for an oil tank.
Oil tanks are used to store petroleum, heavy oil, and other oils, including gasoline and diesel oil in automobile and motorcycle engines.
Since most of these contents are hazardous materials, they must be strictly controlled to prevent ignition or leakage.
Depending on the type, oil caps are usually equipped with a mechanism to release the pressure inside the tank, thus keeping the oil tank at the proper pressure.
Uses of Oil Drain Plugs
Uses of oil drain plugs are as lids and plugs for oil tanks and other oil storage tanks, as evidenced by their other name, oil caps.
The pressure inside an oil tank changes with changes in internal and external temperatures and with increases and decreases in the amount of oil in the tank. Normal oil tanks have a certain level of pressure resistance to withstand these pressure fluctuations, but unnecessary pressure increases or pressure reductions can cause various problems such as oil tank damage or oil leaks.
To prevent such problems, oil drain plugs with a ventilation structure of is used. Specific examples of where oil caps are used include locations where the air pressure in the tank becomes unstable due to temperature or the amount of oil, locations where pressure venting measures are required such as when compressed air is used to control the pressure in the tank, and locations where the depressurization of the tank makes it difficult to drain the liquid.
How to Select Oil Drain Plugs
To select oil drain plugs, it is necessary to consider the material and structure of the oil drain plugs in addition to its shape, which must fit the oil tank.
Oil drain plugs are mainly made of resin, but in areas where there is a risk of explosion, it is necessary to use a material that will not generate sparks that could cause a fire or explosion, and a product that complies with explosion-proof standards. In addition, when used in tanks installed outdoors, ordinary resin oil drain plugs easily deteriorate due to ultraviolet rays and may be damaged by shocks. In such cases, the use of steel-covered or aluminum-covered products with metal covers improves durability.
In addition to products with a normal sealing mechanism, oil drain plugs are also available with a venting mechanism that responds to changes in internal and external pressure. There are various types of products with such venting mechanisms, including those that maintain venting at all times, those that can be manually switched between venting and sealing structures, those that allow pressure settings for intake and exhaust, and those that only perform intake or exhaust, so it is necessary to select the right product for the purpose and application.
