Star circle

• Star seal ring (referred to as star ring), also known as the X-ring, it is formed by vulcanization in the mold its cross section is four sealing lips circular ring, it on the basis of O-ring performance has been improved and improved, its standard size is completely the same as the United States AS568 standard O-ring, can replace most of the O-ring occasions. It is a sealing element that can seal in both directions. When installed in various forms of grooves, the radial or axial precompression gives the initial sealing ability of the star ring, and the sealing force is increased with the increase of pressure. Under the action of pressure, the cross section shape of the star ring will make the pressure transfer evenly to all aspects, so it has a good sealing effect.
