This listing is for a Unitized Oil Seal used on heavy duty axles that install on the back of 10,000 - 15,000 lb Dexter & Hayes hubs. This oil seal has an inner diameter of 3.125 inches and an outer diameter of 4.50 inches, which is designed to fit select heavy duty 8 lug trailer hubs, so it is always a good idea to double check any seal numbers and measurements from your current seal to make sure you are getting an exact replacement.
A Unitized oil seal is a dual action seal because the inner part stays fixed on the spindle and the outer casing rotates with the hub. This seal effectively keeps the oil in your heavy-duty trailer hubs or drums, and prevents dust, water, and other intrusive materials from entering.
