Lubricant jar cap 016 is a tool used to seal off the opening of a container holding lubricant. This mechanism guards against contamination or drying out of the jar's contents. It is often used for sauce cans, dried powder bottles, lubricating oil bottles, motor oil bottles, antifreeze bottles, coolant bottles, paint containers, live oil cans, and more. The top opening of a bottle is closed or sealed with bottle caps. Lubricant jar cap 016 is made to keep the contents contained inside the container without exterior leaks and to guarantee that the product's quality is maintained.
