2. Contamination Control Hydraulic oil is susceptible to contamination from dust, dirt, and other external particulates. Seals act as barriers, keeping harmful substances out of the hydraulic system. This is essential for prolonging the life of hydraulic fluid and components, such as pumps and actuators.

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.

Typically made from high-quality rubber or synthetic materials, oil seals are designed to withstand various operating conditions, including temperature fluctuations and exposure to chemicals. The choice of material affects the seal's durability and effectiveness. Common materials used for oil seals include nitrile rubber (NBR), fluoroelastomer (FKM), and silicone rubber, each offering unique properties suited for specific applications.
