Almost any industrial application will incorporate a gasket. Gaskets create a seal between two surfaces, preventing leaks, either from or into the joined objects. Like many parts used in industrial applications, there are about as many types of gaskets and fluid sealing solutions as there are applications.
Types of gasket materials include metallic, semi-metallic and non-metallic. Each offers a unique strength to maintain the integrity of a seal. Factors like the medium to be preserved, the amount of tension and compression the seal undergoes, and even the materials that are joined play an important role in choosing the right type of gasket for an industrial application.
The Major Types of Gasket Materials
Gaskets are most often made from a flat material sheet that is then cut to fit the surface to be sealed.
A gasket should be able to be compressed as well as form to the sometimes irregular surfaces it is joining. Most gaskets are under intense pressure, which can exceed 2000 psi or higher. One of the truisms of gaskets is that the more compressive load exerted on the gasket, the longer it lasts. Most gasket manufacturers will place their gaskets under a series of high compression tests and publish the results of these tests.
