● Features : 

Our seals are produced with new and high quality raw materials, U-type Y-type seals in the case of low pressure, only rely on the lip of the interference deformation to produce a seal, due to the small contact area, the friction is relatively low, with the rise in pressure, the elastic deformation of the lip increases, tensile, compressive and bending stresses increase, the radial pressure of the U-ring automatically becomes larger, the length of contact with the sealing surface increases until the U-ring axial The U-type Y-ring is the most commonly used oil seal in hydraulic cylinders, it is a typical lip seal, no matter it is used for piston or piston rod, it can obtain a good sealing effect. It is a typical lip seal and can obtain good sealing effect no matter used for piston or piston rod.
Medium: hydraulic oil, emulsion, water.
1、Excellent wear resistance
2、Strong impact resistance
3、Small compression deformation.
4、Improved sealing performance under zero pressure.
5、Suitable for harsh working environment.
6、Good sealing performance and long service life.

●Use For: 

Widely used in hydraulic rods, hydraulic cylinders, pistons, piston rods, cylinders, energy equipment, chemical equipment, engineering machinery, automobiles and so on. It is the best choice for replacing broken oil seals.
