What material is typically used for oil lines?

The typical materials used for oil lines are copper or flexible steel because they are designed to withstand the high pressures and potential corrosive effects of oil. Copper is a preferred choice due to its excellent corrosion resistance and durability, while flexible steel lines provide additional strength and flexibility, making them easier to install in various configurations without risking leaks. These materials also comply with safety standards that ensure the integrity of the oil delivery system, reducing the risk of leaks that can arise from weaker options.

In contrast, using plastic materials for oil lines could lead to issues such as degradation over time due to exposure to heat and oil, which could result in leaks or failures. Similarly, aluminum, while lightweight and resistant to rust, does not have the same strength and durability for pressure applications compared to copper and flexible steel. PVC is not suitable for oil lines as it is not designed to handle the pressures and chemical compatibility required for oil transportation, making it a poor choice for such applications.
