1. Within a certain working pressure and temperature range, the sealing ring should have very good sealing performance. And, with the improvement of pressure, it can automatically improve its sealing performance.
2. The friction between the sealing ring device and the motion parts should be relatively small, and the friction coefficient should be stable.
3. It is good for corrosion resistance, and it is not easy to aging, and its service life is long.
4. To a certain extent, it can automatically compensate by itself.
