The O-ring is a rubber ring with a circular interface shape and is the most widely used seal in hydraulic and pneumatic applications.
O - ring is a two - way sealing element. During installation, the initial compression of the O-ring in the radial or axial direction determines the initial sealing capacity of the O-ring. The force generated by the system pressure acting on the O-ring is the total sealing force; The sealing force increases with the increase of system pressure.
Under pressure, the shape of the O-ring resembles that of a liquid with high surface tension. The pressure is transmitted equally in all directions.
