The Glyd ring is mainly based on its own deformation of the sealing surface to produce a high contact pressure, the organization of no pressure liquid leakage.When the hydraulic cylinder works, the pressure liquid through the O-ring elastic deformation of the maximum extrusion square seal ring, so that it is close to the sealing surface and high pressure, so as to achieve the joint prevent the leakage of pressure liquid.
