Gasket[edit]

A gasket is a mechanical seal that fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow "less-than-perfect" mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials.

Types of Gaskets[edit]

Gaskets come in many different designs based on industrial usage, budget, chemical contact, and physical parameters:

Sheet Gaskets[edit]

Sheet gaskets are cut from a flat sheet of material. They are used in a wide range of applications and can be made from various materials, including rubber, cork, and asbestos.

Spiral Wound Gaskets[edit]

Spiral wound gaskets are made by winding a metal strip and a filler material, such as graphite, together. These gaskets are used in high-pressure applications.

Ring Gaskets[edit]

Ring gaskets are used in flange connections and are typically made of metal. They are designed to withstand high pressures and temperatures.

Materials[edit]

Gaskets can be made from a variety of materials, each suited to different applications:

Rubber[edit]

Rubber gaskets are used in applications where flexibility and resilience are required. They are commonly used in plumbing and automotive applications.

Cork[edit]

Cork gaskets are used in applications where compressibility and flexibility are needed. They are often used in oil and fuel systems.

Asbestos[edit]

Asbestos gaskets were once widely used due to their heat resistance and durability. However, due to health risks associated with asbestos, their use has declined significantly.

Non-Asbestos[edit]

Non-asbestos gaskets are made from materials such as fiberglass, aramid, and PTFE. These materials offer similar properties to asbestos without the associated health risks.

Applications[edit]

Gaskets are used in a wide range of industries and applications, including:

Automotive: Used in engines, transmissions, and exhaust systems.
Aerospace: Used in aircraft engines and fuel systems.
Industrial: Used in pipelines, chemical processing, and power generation.

-Gaskets can be classified in many ways, for example by material, by function, or by application. Some of the most common types of gaskets are:
+=== Sheet Gaskets ===
-* '''Sheet Gaskets''' - These are simple and versatile. They are used in a wide range of applications, from household uses to industrial settings.
+Sheet gaskets are cut from a flat sheet of material. They are used in a wide range of applications and can be made from various materials, including rubber, cork, and [[asbestos]].
-* '''Solid Material Gaskets''' - These are used for high pressure, high temperature applications where the gasket must withstand extreme conditions.
-* '''Spiral Wound Gaskets''' - These are used for high pressure and high temperature applications. They are made by winding a metal strip and a filler material into a spiral shape.
-* '''Ring Gaskets''' - These are used in oil and gas production, as well as in the petrochemical industry.
-==Applications==
+=== Spiral Wound Gaskets ===
-Gaskets are used in a wide variety of applications, including, but not limited to:
+Spiral wound gaskets are made by winding a metal strip and a filler material, such as [[graphite]], together. These gaskets are used in high-pressure applications.
-* '''Piping and plumbing''' - Gaskets are used in piping systems to prevent leaks.
+=== Ring Gaskets ===
-* '''Engines''' - In engines, gaskets are used to seal the cylinder head to the engine block.
-* '''Electronics''' - In electronics, gaskets can be used to prevent dust, dirt, and moisture from entering a device.
