The sealing ring is used in different sealing occasions, and the materials used are different

The sealing ring is a rubber sealing ring with a circular section. Because it is an O-shaped section, it is called an O-ring. Mainly used in hydraulic and pneumatic systems. In different fixed sealing occasions, the seals are equipped with different useful and economical sealing elements. The sealing ring is a bidirectional sealing element. During the operation of the equipment, the initial radial or axial shrinkage imparts the initial sealing performance of the sealing ring itself. O-rings are used in mechanical parts to prevent leakage of liquid or gaseous media in suspension.


The sealing ability of the system pressure and the initial sealing force form the total sealing force, which moves forward as the system pressure increases. The sealing ring can effectively highlight its role in static sealing occasions. In dynamic and appropriate occasions, sealing rings are also widely used, but are limited by sealing speed and pressure. In other cases, the sealing ring can also be used as a dynamic sealing element for axial reciprocation and low rotational motion. In different cases, the material used for the sealing ring is different.

The sealing ring can still play a good role in sealing and damping in environments such as oil, acid, alkali, abrasion, and chemical corrosion. Seals are widely used seals in hydraulic and pneumatic transmission systems. General rubber retardation is minus 20°-30°, that is, silicone rubber still has good elasticity at minus 60°-70°, and our specially formulated silicone rubber can withstand extremely low temperatures. Excellent elasticity and excellent shrinkage, excellent resistance to neutral solvents, high tensile strength after formulation.

Generally, try to choose a large-section sealing ring, because the volume of the sealing ring squeezed into the gap should be less than the allowable value of larger extrusion in the same gap. Sealing rings are widely used in the appearance of machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters. Typically, the device acts as a seal in a groove with a rectangular cross-section on the outer or inner circle.
