Replacement for National 205051 Grease Seal

Published 04/10/2020

Question:

Hello, wondering if you have axle grease seals that are comparable to National #205051 for my classic flatbottom boat trailer. Trailer was built in 1964 and now just in local showings and in the water once or twice a year. I want to replace all 4 seals if you have a interchange part that references the one I mention above. Thank you

From what I could find in my research, a National 205051 grease seal has an inner diameter of 1.72 inches and an outer diameter of 2.565 inches, and we do have a replacement grease seal with exactly those dimensions.

The correct seal for your trailer is the Grease Seal # 58846.

I have added a link to a video review for you to check out as well.
