Wheel hub oil seal is a crucial component of automotive vehicle.it is placed in the front and rear wheel hubs where it acts as a barrier between the axle shaft and the wheels.The primary function of seal is to prevent the leakage of lubrication oil from the wheel hub and keep out dirt,debris and other contaminants that could damage the wheel bearings.without a functioning oil seal,these contaminats can cause serious damage to the bearings,leading to premature wear and tear and eventual failure.
