A metal pressure oil can, often referred to simply as an “oil can,” is a container used to hold and dispense lubricating oil or other fluids. The “500C.C.” in your description likely refers to the capacity of the can, which is 500 cubic centimeters, equivalent to 500 milliliters.

These oil cans typically consist of a metal body, usually made of steel or aluminum, with a pump mechanism and a spout for dispensing the oil. The pump mechanism may vary depending on the design but often involves a plunger or lever that, when pressed, creates pressure inside the can to force the oil out through the spout.

Oil cans are commonly used in automotive maintenance, machinery lubrication, and other applications where precise application of oil or lubricants is necessary. They are preferred in situations where aerosol spray lubricants are not suitable or when more control over the dispensing of oil is required.

When using a metal pressure oil can, it’s essential to ensure that the can is filled with the appropriate type of oil or lubricant and that the pump mechanism is in good working condition to prevent leaks or spills. Proper maintenance, including cleaning and lubricating the pump mechanism as needed, can help ensure the longevity and effectiveness of the oil can.
