2. Contaminant Protection Grease seals act as a first line of defense against contaminants. Dust, water, and debris can enter the bearing assembly and potentially lead to corrosion, pitting, and other forms of wear. By keeping these contaminants out, grease seals help maintain the integrity of the bearings.

When purchasing a seal kit for your hydraulic jack, it is important to make sure that you are getting the correct kit for your specific jack model
. Using the wrong seal kit can result in further damage to your jack, so it is always best to double-check before making a purchase.

The mention of 55%, 80%, and 10% in relation to oil seals might reflect various metrics or considerations concerning their performance and application. For example, in many mechanical systems, seals can be categorized based on their efficiency, effectiveness in preventing leakage, and their material composition. A 55% rating might refer to a baseline performance measure for standard oil seals, whereas an 80% rating could indicate high-performance seals designed for rigorous applications. On the other hand, a 10% figure could relate to the failure rate or the operating conditions under which these seals can be compromised.
