A gasket is a type of sealant used to make a part or structure waterproof. Gaskets are made from two materials: an elastic material and a metal or plastic dough. The elasticity of the dough ensures that the gasket will stay put when tightened, while the metal or plasticreening helps improve heat resistance and protect against corroding.
When making a good gasket, it’s important to first understand what kind of shape your parts need. Your gasket should be shaped like an inverted V, in order to provide maximum moisture and air circulation around your parts. You can also use a W shape for easier installation and removal, while an L shape will help reduce water entry into your parts and ensure long lasting protection.
