①Sealing principle of lip type seals

The lip seal relies on the radial pressure generated by the interference of the seal lip and the pressure of the working medium, that is, the self-tightening effect, so that the seal produces elastic deformation and plugs the leakage gap to achieve the purpose of sealing. It has more significant self-tightening effect than extrusion type seal.

②Product characteristics of lip seals

The structure type is Y, V, U shape. Compared with the O-ring, the structure is more complex, the volume is large, the friction resistance is large, the loading is convenient, the replacement is rapid.

We specializes in the production of high quality seals, our main products are O-ring, Square Rings, X-Rings, Y-rings, U-rings, High precision miniature seals, Bonded Seals, ED seals, hydraulic seals, dust rings, Custom products, shaped rubber gaskets, oil seals, rotating grey ring, rotating St seal, spring energized seal and so on.
