PTFE SPGO piston seals can be used on bores and shafts, but their sealing effect is the same. According to the elasticity of its own material, a high initial contact stress is generated on the sealing surface to prevent liquid leakage. When the hydraulic cylinder is working, the pressure liquid begins to squeeze the square sealing ring to the maximum extent through the elastic deformation of the O-ring, making it close to the sealing surface, resulting in high additional contact stress. This additional contact stress increases with the increase of the O-ring. And increase. The pressure of the pressure fluid increases and, together with the initial contact stress, prevents leakage of the pressure fluid.

1. Good sealing effect, whether it is dynamic sealing or static sealing

2. High pressure resistance, high temperature resistance, and high extrusion resistance

3. The groove structure is simple in design and easy to install.

4. High compatibility, compatible with almost all fluids
