As a critical protective barrier for the steering column, this seal sleeve delivers superior sealing to safeguard internal mechanical and electrical components. Its multi-layered structure features a high-elasticity rubber core that fits tightly to the column surface, forming an airtight, watertight seal. This effectively blocks dust, mud, water, road salt, and debris from entering the steering column housing, preventing corrosion, wear, and damage to gears, bearings, and wiring harnesses. The seal also retains lubricants inside the steering system, ensuring smooth operation and reducing friction between moving parts. It maintains reliable sealing performance across harsh conditions—from muddy construction sites to rainy highways and snowy rural roads—minimizing steering system failure risks and extending component service life.
