Gasket
Gasket
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 for "less-than-perfect" mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials.
Materials[edit | edit source]
Gaskets are normally made from a flat material, a sheet such as paper, rubber, silicone, metal, cork, felt, neoprene, nitrile rubber, fiberglass, polytetrafluoroethylene (otherwise known as PTFE or Teflon) or a plastic polymer (such as polychlorotrifluoroethylene).
Types of Gaskets[edit | edit source]
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 - These are simple and versatile. They are used in a wide range of applications, from household uses to industrial settings.
- 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[edit | edit source]
Gaskets are used in a wide variety of applications, including, but not limited to:
- Piping and plumbing - Gaskets are used in piping systems to prevent leaks.
- 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.
