gasket
A gasket is a mechanical seal that fills the space between two or more mating surfaces, usually to prevent leakage from or into the joined objects while under compression. Gaskets are used to provide a tight, impenetrable seal under these conditions. These gaskets are technologically sophisticated as they can be highly durable, flexible and resistant to wear and tear. These can be made from rubber, metal or composite materials for well-defined industrial use. Gaskets are a core element to industries like automotive, aerospace, and manufacturing that rely upon them for engine, transmission and other mechanical assemblies in order to operate reliably and endure performance.
