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.

From an ecological perspective, seal dust plays a crucial role in nutrient cycling within marine environments. The organic matter released into the ecosystem can serve as a food source for various microorganisms, subsequently supporting the entire food web. Phytoplankton, the primary producers of marine environments, benefit from the nutrients in seal dust, which can enhance their growth and, in turn, bolster the populations of herbivorous marine organisms.

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
