Petroleum oil, also known as mineral oil, is a hydrocarbon based oil derived from petroleum. It is commonly used as a lubricant and coolant in industrial and automotive applications. Petroleum oil is also used in the production of rubber and plastic parts, as well as in paints, varnishes, and coatings.
When exposed to temperatures above 250°F, rubber can become brittle and eventually crack and fail. This can cause rubber seals to fail, leading to leaking and other problems. Additionally, exposure to high temperatures can cause rubber to swell, which can lead to sealing failure, as well as cause deformations in rubber parts.
