It has a wide range of applications, if the material is properly selected, it can meet the requirements of various media and various motion conditions.
O-ring is a kind of extrusion seal. The basic working principle of extrusion seal is to rely on the elastic deformation of the seal, resulting in contact pressure on the sealing contact surface. The contact pressure is greater than the internal pressure of the sealed medium, and no leakage occurs, otherwise leakage occurs.
