Pu seal‘s Advantage (1)

Good compatibility. Due to the long-term immersion in hydraulic oil, it is easy to swell, dissolve or embrittle harden and so on, so that it can not seal the sealing effect. Therefore, it is required that the hydraulic seal has good compatibility with hydraulic oil.

Pu seal‘s Advantage (2)

Friction resistance is small. In order to avoid or reduce the hydraulic equipment to produce low pressure crawling and other undesirable phenomena, requiring hydraulic seals with low static friction and dynamic friction resistance, and its friction coefficient should be very stable.

Pu seal‘s Advantage (3)

Long service life. Hydraulic seal should have good flexibility, heat resistance, cold resistance, pressure resistance, wear resistance and a certain degree of physical and mechanical strength, and long service life.

Pu seal‘s Advantage (4)

Hydraulic seal leakage is very small, with a good sealing effect, and with the hydraulic oil pressure increases automatically improve its sealing effect, even in high pressure and high temperature and other harsh working environment, the hydraulic seal leakage is also no obvious increase.
