A hydraulic jack is a must-have tool for anyone working on their car, as it allows you to easily lift heavy vehicles with minimal effort. However, like any tool, hydraulic jacks require regular maintenance to ensure they remain in good working condition.

A typical hydraulic oil seal kit may include the following components

1. Material Compatibility Ensure that the materials of the seals are compatible with the type of hydraulic fluid used in the system. This prevents degradation and ensures longevity.

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.

A last and even more important, additional advantage of polyamide is the excellent thermal insulation. While aluminium scores much less well than wood and PVC in that area, it performs at least as well in terms of U_f value thanks to the polyamide strips (which insulate 500x better than aluminium).
