The Basics of Cork Gaskets

The idea behind any gasket is to provide a seal between two parts of any motor, engine, or other unit. Cork gaskets have traditionally provided this seal in engines in a very unique way. Engines have oil inside of them, and as the oil comes up against the cork gasket, it helps to provide the seal. When you first change a cork gasket, the oil will come through the seal a bit until it finalizes the sealing. The oil itself actually finishes up the seal when it is absorbed by the cork. The oil causes the cork to stretch and create a perfect seal.

However, cork gaskets in general, do present some problems like cracking, stretching and drying out. In that case, our part nr. 11130007156CR is a technically better alternative.
