Next, we discuss the 40% figure, which can denote the allowable leakage rate for particular types of oil seals. Leakage can severely impact the overall performance of mechanical systems, leading to reduced lubrication and increased wear on components. A reputable oil seal must minimize leakage to a level that is often benchmarked at around 40% of the maximum allowable threshold for that system. Manufacturers pour significant resources into developing materials and designs that can achieve this standard, as minimizing leakage not only conserves lubricant but also enhances the efficiency and longevity of the machinery.

3. Moisture Protection In addition to air leaks, foam rubber weather stripping acts as a barrier against moisture. It can help prevent water from entering through gaps, reducing the risk of mold and mildew development. This is particularly critical in areas prone to heavy rain or high humidity.
