There are various types of hydraulic dust seals available, including piston seals, rod seals, and wiper seals. Each type serves a specific purpose in maintaining the cleanliness and efficiency of hydraulic systems. For example, piston seals are used to prevent fluid leakage and contamination around the piston, while rod seals prevent fluid leakage along the rod in hydraulic cylinders

hydraulic dust seal. Wiper seals, on the other hand, are designed to wipe away dirt and debris from the rod before it enters the hydraulic system.

The dimensions of the oil seal, 20x35x7, refer to its inner diameter, outer diameter, and thickness. These specifications determine the compatibility and performance of the seal in different applications. The size of the oil seal must be carefully matched to the shaft or housing it is intended to seal to ensure a proper fit and effective function.

The percentage of an oil seal refers to its ability to effectively prevent leakage. A higher percentage indicates a better sealing capacity, with 100% being the ideal value. However, in reality, achieving a perfect seal is often challenging. Therefore, oil seals with percentages ranging from 25% to 35% are commonly used in applications where a high level of sealing performance is required.
