The gasket is a thin plate (usually round) with a hole (usually in the middle) that is usually used to distribute the load thread fastener.Other uses are as spacers, springs (Belleville gaskets, wave gaskets), wear pads, pre-display devices, and locking devices.Rubber gaskets are also used in faucets (valves) to cut off the flow of liquid or gas.Rubber or silicon gaskets can also be used to reduce fan vibration.Usually the outer diameter of the gasket is about twice the inner diameter.
