3 Gasket Types You Should Know

Blown head gaskets are a common car problem. How Stuff Works defines the head gasket as a seal you fit in between your piston cylinder head and engine block. Without it, the combustion process inside your car’s engine won’t be sealed, allowing coolant as well as engine oil to mix together in the combustion chamber, leading to engine malfunction.

Function

That’s basically what gaskets are. They’re seals. You use these seals to ensure no leaks get through. Whether you’re trying to fix your car or toilet, a gasket is essential to the operation of many things around you.

Types

There are plenty of gasket types available in the market. You’ll probably need to note down what kind of sealing capacities you need, whether you must seal in liquids or solids. Glass, cork, metal and rubber or even silicone—you can opt for any of these.

Rubber

Available in tube form, a rubber gasket is the ideal choice for operations that require a tight seal, especially silicone rubber gasket. It’s the go-to option for kitchen, bathroom or outdoor work that need the use of gaskets. Since silicone cures once it’s exposed to air, it’s ideally well suited for use in cars as well, not just inside homes. It’s well able to take on low temperatures or high ones in a furnace, making it the best kind of seal for a number of applications.

Metal

Need gaskets suited for high temperature operations? Metal gaskets are your best bet. These gaskets can expand and contract, which allows it to mate to the surrounding surfaces, creating an effective seal.

Cork

Best used for sealing operations in low temperature. It makes for a good seal because the material’s compression strength is high, though the material is a bit more fragile if you try to bend it.
