The material of the seal must be compatible with the medium in contact with it. Why? What is compatibility? Thank you
Therefore, the compatibility between them requires simple understanding that they do not react to each other in order to maintain their respective characteristics.
For example, three Yuan rubber sealing material is good, can withstand a certain corrosive acid, so it can be used to seal the acidic decomposition medium such as high voltage gas insulated SF6, but if used to seal the aviation hydraulic oil will fail because of three EPDM not resistant to oil, then we must choose nitrile rubber.
The material of the seal is rubber, there are metal sealing ring, no matter what sealing form, if the material choice is wrong, the sealing ring and the sealing medium chemical reaction, then it will make the seal failure
