Product Description

USH type sealing ring in the low pressure, only by the lip of the interference deformation to produce sealing, because the contact area is small, the friction is relatively low, as the pressure rises, the mouth elastic deformation increases, the tensile, compressive and bending stress increases, the radial pressure of the U-ring automatically becomes larger, and the sealing surface of the contact with the length of the sealing surface continues to increase until the U ring of the entire axial length of the sealing surface in contact with the sealing surface, so as to ensure that the high-pressure state has a good This ensures good sealing under high pressure. These seals are the most commonly used oil seals in hydraulic cylinders, and can be used to obtain good sealing regardless of the piston or piston rod.

 Product Features

-Selected high-quality hybrid rubber, high rubber content, with good hardness and wear resistance, even in very poor working conditions, still durable


-Resistant to high vacuum and high temperature, suitable for relatively high temperature environments up to 250°C. Good stability, good electrical properties, small air permeability.


-Acid and alkali resistant to a variety of chemicals, has good chemical resistance, especially all the acids, aliphatic hydrocarbons, aromatic hydrocarbons and solvents (except ketones, vinegar)


-Precise size, small error, good sealing performance, smooth surface trimming fine, smooth texture, no obvious burrs and pungent taste can be used for a long time to keep the colour does not fade!
