Washers are generally flat metal rings used to protect the surface of the connected parts from being scratched by the nuts, dispersing the pressure of the nuts on the connected parts. The gasket is a mechanical seal between two objects, which is usually used to prevent the impact of pressure, corrosion and pipeline natural thermal expansion and contraction leakage between two objects. The materials of rubber gaskets usually include Nitrile rubber, styrene butadiene rubber, hydrogenated Nitrile rubber, EPDM, silica gel, fluorine rubber, neoprene, perfluorocarbon, etc. Gaskets are usually made of sheet materials, such as pad paper, rubber, silicone rubber, metal, cork, felt, Neoprene, Nitrile rubber, glass fiber or plastic polymer.
