I see you were looking at another of our Q&A pages regarding the Grease Seal # GS-2250DL with a 2.250" inner diameter and 3.376" outer diameter replacing a seal marked TB 2.250 3.371. The slight difference in the outer diameter is likely do the difference in material used to create the seal. As different metals all have different amounts of expansion and shrinking when it gets hot or cold they could be slightly different. As the seals are only 5 thousands of an inch difference this will not create any issues when pressing the seal into the hub.
