Purchase rubber seals - O-ring seals

2023-08-23
After rubber products are produced and formed, there will be product burrs on the products. The rough edge treatment of rubber products has high requirements for product appearance on the one hand, and is also inevitably related to product prices on the other hand. The processing of rough edges in general rubber products also incurs production costs for manufacturers. Therefore, while ensuring product quality in the process of processing rough edges, manufacturers pay more attention to the efficiency of processing rough edges in rubber products.
O-shaped sealing ring is a circular rubber sealing ring with a circular cross-section. Due to its O-shaped cross-section, it is called an O-shaped sealing ring. Mainly used for preventing the leakage of liquid and gas media in mechanical components under static conditions. In some cases, O-ring seals can also be used as dynamic sealing components for axial reciprocating and low-speed rotational motion. According to different conditions, different materials can be selected to adapt to them, making it a widely used type in hydraulic and pneumatic transmission systems.
When selecting O-ring seals, it is recommended to choose O-rings with a large cross-section as much as possible. Under the same gap, the volume of O-ring seals squeezed into the gap should be less than the maximum allowable value.
For different types of fixed or dynamic sealing applications, O-ring seals provide designers with an effective and economical sealing element. O-ring is a bidirectional sealing element. The initial compression in the radial or axial direction during installation endows the O-ring with its own initial sealing ability. The sealing force generated by system pressure and the initial sealing force combine to form the total sealing force, which increases with the increase of system pressure. The O-ring plays a prominent role in static sealing situations. However, in dynamic and appropriate situations, O-rings are often used, but they are limited by the speed and pressure at the sealing point.
