Hebei Hankai 25 40 7 seal

4. Gaskets Gaskets are essential for sealing joints between different components of the hydraulic system. They prevent fluid leaks and maintain system integrity.

7. Reinstall the Boom Cylinder Once the cylinder is reassembled, lift it back into place using the hydraulic jack. Reattach it to the excavator by securing the pins and bolts. Make sure everything is tightened to the manufacturer's specifications.

One of the primary characteristics of high temperature oil seals is their ability to maintain flexibility and resilience at elevated temperatures. Traditional rubber seals may become brittle and lose their sealing capabilities when exposed to heat. In contrast, high temperature oil seals retain their mechanical properties, ensuring that they continue to perform their sealing function effectively even in harsh conditions. Typically, these seals can withstand temperatures ranging from 150°C to over 300°C, depending on the specific material used.

Seal dust primarily accumulates in areas with high seal concentrations, such as beaches and ice floes. As seals molt and shed skin, fur, and other organic materials, these particles become airborne, mixing with the surrounding environment. The composition of seal dust includes not only the biological debris from the seals but also microorganisms and other particulates that they may encounter in their habitat. This composition can vary significantly depending on the species of seals present, their diet, and the environmental conditions of the area.
