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.

Potassium sorbate is generally recommended as safe to consume, according to the FDA and the CSPI. Defined as a food additive and preservative, it’s used in very small quantities. Although the specific amount varies by manufacturer, federal law dictates that a product cannot contain more than 0.3 percent potassium sorbate by weight, notes the USDA.
