What does an oil seal do in a trailer hub?

An oil seal keeps lubricant inside the hub and prevents dirt and water from entering, which protects bearings and extends axle life.

How do I measure for the correct oil seal?

Measure the inner diameter (fits over spindle) and outer diameter (fits into hub bore). You can also match the part number from your old seal.

Are oil seals compatible with both grease and oil-filled hubs?

Some seals work for both types, but it’s best to choose a seal specifically designed for your lubrication method—grease or oil bath.
