Gaskets are mechanical seals between two objects, typically to prevent pressure, corrosion, and natural thermal expansion and contraction leakage of the tubing between the two objects. Since the machined surface may not be perfect, the irregularities can be filled using shims. One leak (usually in the middle) where a washer is a thin plate (usually circular) is usually a load thread fastener for distribution. Other uses are as spacers, springs (bellville washers, wave washers), wear pads, pre-displays, lock devices. Rubber gaskets are also used in faucets (valves) to shut off flowing liquids or gases. Rubber or silicon gaskets may also be used to reduce fan vibration. Typically the outside diameter of the gasket is about twice the inside diameter.
