Installation and maintenance

During installation: Make sure that the size of the seal matches the contact surface. Too tight or too loose will affect the sealing effect; keep the contact surface clean to prevent impurities from affecting the sealing performance.

In use: Check the wear of the seal regularly. If aging or damage is found, it should be replaced in time; avoid long-term exposure to extreme environments, such as high temperature, strong acid and alkali, to extend the service life.
