Question: What is the difference between a gasket and an O-ring?
A gasket and an O-ring are both types of seals used to prevent leaks in machinery or equipment, but they differ in their shape, material, and application.
An O-ring is a circular or toroidal shaped seal made of rubber, silicone, or other elastomers that is used to seal a fluid or gas between two or more mating surfaces. O-rings are typically used in dynamic applications, meaning that they are used in components that move or rotate, such as pistons, cylinders, and valves.
A gasket, on the other hand, is a flat or irregularly shaped seal that is placed between two or more mating surfaces to create a static seal. Gaskets are made of a variety of materials such as rubber, cork, silicone, or metal and are used in a wide range of applications, including engines, pipes, and electronics.
The main differences between a gasket and an O-ring are their shape and application. O-rings are circular or toroidal in shape and are used in dynamic applications, while gaskets are flat or irregularly shaped and are used in static applications. Additionally, O-rings are typically made of rubber or other elastomers, while gaskets can be made of a wider range of materials depending on the application.
In summary, while both gaskets and O-rings are types of seals used to prevent leaks, they differ in their shape, material, and application.
