- The inclusion of 7% steel, often in the form of a metallic insert or spring, further fortifies the oil seal's performance
20 30 7 oil seal. Steel provides the necessary rigidity to withstand mechanical stress and maintain the seal's position within the machinery. It aids in preventing the seal from extrusion, particularly in scenarios where there is significant pressure acting against it.

Spring Seals
- A steering oil seal, primarily made from high-quality rubber or synthetic materials, is designed to seal the interface between the steering gear and the steering shaft. It prevents oil, the lifeblood of the power steering system, from leaking out and contaminants like dirt, dust, and water from infiltrating the system. This is essential because any compromise in the sealing can lead to reduced steering efficiency, increased wear on components, and, in extreme cases, total failure of the power steering system.
For more severe oil-seal service at temperatures of 160°C (320°F) or higher for extended periods, more resistant fluoroelastomer compositions are required for long service life. High-fluorine VDF/PMVE/TFE elastomers, along with TFE/olefin FEPM elastomers, are much less susceptible to attack by oil additives. TFE/P fluoroelastomers have the requisite chemical resistance, but have low fluorine content, leading to relatively high swell and to soft vulcanizates with lower wear resistance than desired.

Silicone
Wide temperature range
Commonly used in low temperature applications
Very prone to mechanical damage during fitting
The sealing process involves the interaction between the rotating shaft and the elastomeric material, resulting in a dynamic barrier that prevents fluid leakage and maintains system integrity.
