What is the function of O-ring

Function of O-ring:

1. The O-ring shall have good sealing performance within the working pressure and certain temperature range, and the sealing performance can be automatically improved with the increase of pressure.

2. The friction between O-ring device and moving parts shall be small and the friction coefficient shall 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 aging, has long service life, good wear resistance, and can be automatically compensated to a certain extent after wear.

4. The O-ring is simple in structure, easy to use and maintain, so that the seal ring has a longer life.

5. O-ring has good self-lubricating performance and can be used for oil-free lubrication.
