Replacement Grease Seal for Dexter Trailer Hub 8-258

Question

Question:

I have a 2017 Little Guy Trailer with 8-258 hubs and the EZ lube system. I am finding that the inner Grease seal for the 1 1/16 straight axel could have a 1.25inch I.D. seal or a 1.50inch I.D. seal which is correct and why the difference? Please disregard the first photo it was a mistake and I do not know how to get rid of it.
