A gasket prevents leakage. Gaskets are a mechanical seal which fills the space between two or more joining surfaces while under compression. Some gaskets are made to withstand oil, water, antifreeze, electromagnetic and radio frequency interference. Gaskets must be chemically attuned with the two joining surfaces to ensure a tight seal with no fluid or gas leaks. Gaskets are used in various industries including automotive, aerospace, aviation, marine, industrial, and electronics among others. Gaskets are also used in engines, compressors, turbines, valves and pumps. Gaskets are of various types and come in different designs, purely dependant on industrial usage, budget, chemical contact and physical parameters.
