Cometic Rear Main Seals

3.27 out of 5 stars 15 Customer Reviews

Keep your oil from escaping with rear main seals from Cometic Gasket. If you have a wet spot on the rear of your oil pan, spots on your driveway, or garage floor, or worse, an oil-covered transmission, then you'd better get rear main seals from Cometic. They are made from heat-resistant, chemical-resistant Viton® material and are available in one and 2-piece seal styles. When you need superior gaskets for your high performance vehicle, Cometic has the gaskets and rear main seals to fit your application.
