Advantages of editing Voice

1. The sealing ring should have good sealing performance within the working pressure and a certain temperature range, and can automatically improve the sealing performance as the pressure increases.

2. The friction between the sealing ring device and the moving parts should be small, and the friction coefficient should be stable.

3. The sealing ring has strong corrosion resistance, not easy to age, long working life, good wear resistance, and can automatically compensate to a certain extent after wear.

4. Simple structure, convenient use and maintenance, so that the sealing ring has a longer life.
