Usage Instructions

1. Select the appropriate silicon carbide seal ring according to the design size and working environment, so as to avoid premature aging of the seal ring and reduce the service life of the seal ring;

2. Clean the dust and impurities of the silicon carbide seal ring and the mating surface before installation, to ensure the service life of the silicon carbide seal;

3. Install the sealing ring in the correct direction, so as not to cause poor sealing effect;

4. The ambient temperature of the silicon carbide seal ring should not exceed the maximum use temperature, if the temperature is too high, it will cause the aging of the seal and reduce the service life of the seal ring.
