This is an O-ring rubber seal. O-rings are round rubber seals with a circular cross-section that are used to prevent the leakage of fluids or gases in a wide range of applications. They are commonly used in hydraulic systems, engines, plumbing, and many other industries due to their simple design and effectiveness in creating a tight seal. **

The type of seal to be used depends on the specific application and requirements. Rubber seals are typically more flexible and provide a better seal against liquids and gases, making them suitable for applications where a tight seal is necessary. On the other hand, fiber rings are more rigid and can withstand higher temperatures, making them ideal for applications where heat resistance is important. Ultimately, the choice between a rubber seal and a fiber ring should be based on the specific needs of the application. **

You can seal the top of rubber boots by using a waterproof sealant or adhesive. Apply the sealant or adhesive around the top edge of the boots and allow it to dry completely. This will create a barrier that prevents water from seeping into the boots from the top. Additionally, you can also use rubber boot cuffs or gaiters to further seal the top of the boots and provide extra protection against water. **
