Are O-rings gaskets?
By definition, an O-ring is technically a gasket, but not all gaskets are O-rings. O-rings are made exclusively of an elastomer material, resulting in an elastic texture that’s able to stretch and revert back to its natural shape and size without breaking. Gaskets, on the other hand, can be made of any material.
Is a gasket and a seal the same thing?
What is a Gasket? Gaskets seal a connection between two components or flanges that have flat surfaces, while seals are used between engine parts, pumps, and shafts that rotate. Gaskets are used wherever a union or flange is required to prevent leaking. Gaskets are most commonly used as static seals.

What is the purpose of gasket?
By definition, a gasket is a mechanical seal that fills the space between two or more mating surfaces, often to prevent leakage while the joined objects are under compression. So, essentially, gaskets fill in the spaces where components of a machine or fixture have gaps.
Why do gaskets fail?
What causes it to fail? One cause of head gasket failure is pre-ignition. As fuel is combusted at unwanted times during an engine’s cycle, large pressures can occur within the cylinder head as the engine begins to work against itself. These spikes in pressure can put strain across the head gasket, causing it to fail.

Metal Gaskets generally leak because of the constant exposure to high temperature and high pressure. One of the main reason is the joint exceeding the capabilities of the gasket. The only true way to stop a leaking head gasket is to replace it.
Do metal gaskets need sealant?
Sealant: None. Only small amounts of high-tack liquid sealant should be used in strategic areas to hold the gasket in place. Also, sealant can extrude out when the gasket is compressed, and it could end up in an oil or coolant passage and restrict or block flow.

How do metal gaskets work?
An elastomeric gasket is a component that seals against the release or inlet of both gases and liquids, creating a seal between two surfaces. They are ideal for filling deformities and connecting two surfaces together. In order to seal precisely, metal gaskets must most of the time be compressed at a higher stress.

Metal and malleable material gaskets (like are found in GM intake gaskets), can be reused if there isn’t any apparent damage to them. In the case of metal or malleable, you’re in good shape most of the time. Once in a while, the gasket, even while looking completely good, will still leak.
Are metal head gaskets better?
The stronger the head gasket, the more difficult it can be for it to make a good seal on the surface of your engine block. If your block isn’t perfectly flat it may be worth using a softer head gasket to will seal more easily even if it won’t handle temperatures and pressures as high as, say a metal head gasket.
