The O-ring is referred to as the O-Ring Seals, which is a rubber ring with a circular cross-section. O-Ring Seals Manufacturers is the most widely used seal in hydraulic sealing and pneumatic sealing systems. O-ring seals have good sealing performance and can be used for both static seals and reciprocating seals; they can not only be used alone, but also are the basic components of many combined sealing devices. It has a wide range of applications. If the material is properly selected, it can meet the requirements of various motion conditions. The working pressure can range from a vacuum of 1.333×105Pa to a high pressure of 400MPa; the temperature range can be from -60°C to 200°C.

The O-ring specification marking method is: inner diameter Фi × wire diameter d , for example: O-ring 20*2.4, Ⅱ-2 GB1235-76, 20 means the inner diameter of the large ring is 20 mm, 2.4 means the section diameter of the rubber ring is 2.4 mm, II-2 represents the type of rubber used, GB1235 represents the standard number, and 76 represents the year when the standard was published. Effective sealing of chemical media. The temperature range is wide (-60℃～+220℃), and the pressure can reach 1500Kg/cm2 in fixed use (used together with the reinforcing ring).
