The material selection of the sealing ring is directly related to its performance and service life. Common sealing ring materials include rubber, silicone, polytetrafluoroethylene, etc., each material has its unique advantages and disadvantages and application scenarios. For example, the rubber sealing ring has good elasticity and sealing performance, which is suitable for most normal temperature and pressure working environment; The silicone sealing ring has better high temperature resistance and is suitable for sealing needs in high temperature environments.

In order to optimize the performance of the sealing ring, in addition to choosing the right material, it can also improve the sealing effect and service life by improving the production process and improving the processing accuracy. At the same time, with the continuous development of new material technology, there will be more high-performance sealing ring materials in the future, providing more protection for the safe operation of mechanical equipment.
