The advantage of sealing ring
1. sealing ring in a certain temperature range working pressure and shall have good sealing performance, and with increasing pressure to automatically improve the sealing performance. 2. the ring device and less friction between the moving parts, friction coefficient should be stable. 3. sealing ring strong corrosion resistance, anti-aging, long service life, good resistance to abrasion, wear and can automatically compensate to a certain extent. 4. simple structure, use, easy to maintain, so seals have a longer life expectancy.
