Rubber sealing rings are generally "Ο"-type rubber parts, and the cross-section is mostly circular. Compared with the skeleton oil (water) seal, the structure is simple, neither skeleton nor self-tightening spring, relying on the flexibility and elasticity of the rubber itself Seal it up.

Oil seal is a general term for products that function as a sealing system, which mainly include O-rings, oil seals, PTFE oil seals, dust rings, etc.

Rubber has many uses in many fields. Whether it is in industry or in life, we can see rubber products everywhere. Just in order to fully understand the use of rubber, it is necessary to carefully classify the use of rubber.

The O Ring is an extruded seal. The basic working principle of the extruded seal is to rely on the elastic deformation of the seal to cause contact pressure on the sealing contact surface.
