A washer is a mechanical seal between two objects that is normally used to prevent pressure, corrosion, and natural thermal expansion and contraction between the two objects. Because the machined surface is not perfect, the use of spacers can fill irregularities. Gaskets are usually made from sheet materials such as paper pads, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, glass fiber or plastic polymers (such as polytetrafluoroethylene). Application-specific gaskets may contain asbestos.
A washer is a hole (usually in the middle) of a thin plate (usually round) that is usually a load thread fastener for dispensing. Other uses are as spacers, springs (Bellville gaskets, wave pads), wear pads, pre-display devices, and lock devices. Rubber gaskets are also used in faucets (valves) to cut off flowing liquids or gases. Rubber or silicone gaskets can also be used to reduce fan vibration. Usually the gasket outer diameter is about twice the inner diameter.
