Does Trailer Hub Seal Width Need to be Measured to Pick Out Replacement

Published 01/05/2023

Question:

Is the OD and ID the only measurements needed to find the correct seal? Is the thickness also important?

Inner and outer diameter of grease seal is the most important. The outer diameter being more exact since the inner can be harder to get an exact figure on since it's rubber there and can be somewhat stretched or hard to measure. The thickness is not something you need to worry about as there aren't different seals available with varying thicknesses for different applications. Using a caliper like the part # PW80157 would give you the exact enough measurement you'd need.

I attached a link to all of our grease seals for you to check out as well. You'd need to use the filters on the page to select your dimensions.
