Gaskets

The purpose of a gasket is to act as a seal filling the space between two or more mating surfaces, in order to prevent leakage from or into the joined objects. This sealing action is usually achieved when the gasket is under compression. Because of the range of applications that gaskets can be used for the material and type of gasket will vary.  

Gaskets are commonly produced by cutting from sheets of flat materials like paper, rubber, silicone, metal, cork, felt, fiberglass, PTFE or a plastic polymer to fit between the joining parts. The properties of the gasket material determine the type of sealing achieved and the material is selected according to the application and conditions (heat, pressure etc.) where the gasket is used. Types of gasket include spiral-wound, cork gaskets, PTFE, graphite and rubber gaskets.

Gasket brands include Burgmann, Lamons, Donit Tesnit, Leader, Econosto, Garlock, Flexitallic, James Walker.
