The O-ring is abbreviated as an O-ring and is a rubber ring with a circular cross section. O-rings are the most widely used seals in hydraulic and pneumatic sealing systems. O-rings are well sealed and can be used in both static and reciprocating seals; they can be used alone and are an essential part of many combined seals. Its wide application range, if the material is properly selected, can meet the requirements of various sports conditions, the working pressure can be from 1.33 × 105Pa vacuum to 400MPa high pressure; temperature range can be from -60 ° C to 200 ° C. The O-ring seal specification method is: inner diameter Фi × wire diameter d, such as: O-ring 20*2.4, II-2 GB1235-76, 20 represents a large circle inner diameter of 20 mm, 2.4 represents the cross-sectional diameter of the apron 2.4mm, II-2 stands for the type of rubber used, GB1235 stands for the standard number, and 76 stands for the standard publication year. By selecting the right rubber material and proper formula design, it can realize oil, water, air, gas and various kinds. Effective sealing of chemical media. The temperature range is wide (-60 °C ~ + 220 °C), and the pressure can be up to 1500Kg/cm2 in fixed use (combined with reinforcing ring). This is a simple overview of the O-ring seal. From here we can have a simple understanding of the O-ring seal, but how is the seal, we have no specific instructions here, you can specifically view other news, O The product advantage of the shape seal.
