The Oil Hubcap O Ring Seal retains lubricant inside the wheel hub and prevents the entry of dirt, water, and other contaminants. Installed between the hubcap and the hub, it ensures that wheel bearings remain properly lubricated, reducing friction, wear, and the risk of premature failure. They maintain their integrity under extreme temperatures, loads, and continuous rotational forces. Its secure fit prevents leaks during high-speed operation for optimal bearing performance.Attributes:• Prevents pressure loss in sealed hub assemblies.• Reduces risk of sudden bearing failure.• Provides a secure fit between the hubcap and hub.Applications: An Oil Hubcap O Ring Seal is installed between the wheel hubcap and the wheel hub, sealing the hub assembly to retain lubricant and prevent contaminants from entering, thereby protecting wheel bearings.
