Wholesale Import rubber o-rings production factory O-ring seal is referred to as O-ring, which is a rubber ring with a circular cross-section. O-ring is the most widely used seal in hydraulic and pneumatic systems.

　　O-rings have good sealing performance and can be used in both static sealing and dynamic sealing; they can not only be used alone, but also are the basic components of many combined sealing devices. Wholesale Import rubber o-rings production factory has a wide range of products, and if the material is selected properly, it can meet the requirements of various media and various sports conditions.

　　The O-ring is an extrusion type seal. The basic working principle of the extrusion type seal is to rely on the elastic deformation of the seal. Wholesale Import rubber o-rings production factory causes contact pressure on the sealing contact surface, and the contact pressure is greater than that of the seal. If the internal pressure of the medium, no leakage will occur, otherwise, leakage will occur.

　　O-rings are typical extrusion seals. The compression ratio and elongation of the O-ring section diameter are the main contents of the seal design, which are of great significance to the sealing performance and service life. The good sealing effect of the O-ring depends largely on the correct matching of the size of the O-ring and the groove size to form a reasonable amount of compression and tension of the sealing ring.
