What material is commonly used for gaskets to ensure engine seal integrity?

Rubber is commonly used for gaskets in engine applications due to its excellent flexibility, elasticity, and ability to compress. These characteristics allow rubber gaskets to form a tight seal between mating surfaces, which is essential for preventing leaks of oil, coolant, and air. Rubber also exhibits good resistance to heat and various automotive fluids, making it suitable for use in different parts of an engine where sealing integrity is crucial.

In addition to its sealing properties, rubber gaskets can withstand vibration and thermal expansion, which are prevalent conditions in engine operation. This adaptability ensures long-term performance and reliability, making rubber a go-to material in various automotive gasket applications. Other materials like metal, paper, and plastic have specific applications but may not provide the same level of seal integrity and durability required in many engine environments.
