The Working Principle of O-ring

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

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

3. The O-ring has strong corrosion resistance, does not corrode the contact surface, does not pollute the medium, is not easy to age, has a long working life, good wear resistance, and can automatically compensate to a certain extent after wear.

4. The O-ring has a simple structure, is easy to use and maintain, and has a longer life.

5. The O-ring has good self-lubricating performance. It can be used as an oil-free lubricated seal.
