Automotive vacuum pump sealing ring material mainly includes polymer materials, such as butyl rubber, fluorine rubber, silicone rubber and so on. These materials have good wear resistance, corrosion resistance and high temperature resistance, suitable for different kinds of vacuum pumps
The function of the auto vacuum pump seal is to prevent the vacuum pump from leaking during the working process. The main function of the sealing ring is to ensure the normal operation of the vacuum pump, extend its service life, and improve work efficiency 1.
In addition, the material selection of the sealing ring has an important impact on its performance. which can withstand high temperatures and pressures, and show excellent stability against a variety of chemicals
