Dust Seal NBR

The dust ring is commonly known as the Seal ring, also known as the Dust Seal. The dust-proof ring is mainly a rubber Sealing ring that can prevent dust and dirt from entering. It is widely used in vehicles, mechanical equipment and construction machinery.

Dust seal is very important for the protection of some hydraulic equipment. If some dust enters the hydraulic equipment, it will not only wear the Sealing ring, but also wear some guide sleeves and piston rods seriously.

In addition, if these impurities enter the hydraulic medium, they will also have a certain impact on the function of the operating valve and pump. If the situation is worse, many of them may damage these equipment.

After using the dust ring, the dust and debris on the piston rod can be effectively removed, but the oil film on the piston rod will not be damaged, which is conducive to the lubrication of the seal ring.
