The Gree ring is composed of a rubber O-ring and a polytetrafluoroethylene ring. The material is PTFE + NBR. In special cases, the rubber elastomer nitrile rubber NBR adopts fluorine rubber FKM. It can be divided into grid ring for hole and grid ring for shaft, but its sealing effect is the same. According to its own deformation, it will produce higher initial contact stress on the sealing surface, preventing the leakage of pressureless liquid. When the hydraulic cylinder is working, the pressure liquid squeezes the square sealing ring to the maximum extent through the elastic deformation of the o-shaped sealing ring, so that it is close to the sealing surface and generates a higher additional contact stress that increases with the pressure of the pressure liquid. Together with the initial contact stress, the leakage of the pressurized liquid is prevented.

The main professional processing equipment includes flat vulcanizer, injection molding machine, rubber and plastic pressurized kneader, rotorless vulcanizer, tensile testing machine...
