Durable Cork-Rubber Gasket Material

This transmission oil pan gasket is made from cork-rubber, a material known for its flexibility and resistance to oil and heat. The cork-rubber composition allows the gasket to conform to the transmission oil pan surface, creating a tight seal that helps prevent fluid leaks. The material also withstands the thermal expansion and contraction common in transmission systems, maintaining integrity over time.
