Seals should exhibit good sealing performance within the working pressure and a specific temperature range, and automatically enhance their sealing capability with increasing pressure.

2. The friction between the seal ring assembly and moving parts should be minimal, with a stable coefficient of friction.

3. Seals have strong corrosion resistance, are resistant to aging, offer a long service life, and have good wear resistance. They can also automatically compensate to some extent after wear.

4. Simple structure for easy use and maintenance, extending the lifespan of the seal rings.
