Difference between gasket and gasket (physical foaming gasket)


A gasket is a mechanical seal between two objects, usually used to prevent pressure, corrosion, and natural thermal expansion and contraction between the two objects. Since the machined surface is not perfect, the gasket can be used to fill the irregularities. The gasket is usually made of sheet material such as mat paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass or plastic polymer (such as polytetrafluoroethylene).


A washer is a hole (usually in the middle) of a thin plate (usually in the middle) that is typically a load thread fastener for dispensing, a part that is padded between the connector and the nut, typically a flat metal ring. Other uses are as spacers, springs (Belleville gaskets, wave gaskets), 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 silicon gaskets can also be used to reduce fan vibration. Usually the outer diameter of the gasket is about twice the inner diameter.
