Features:
Seal numbers are not always listed the same way across axle and hub brands, so the cross-reference data gives you another way to confirm the replacement before the hub comes apart. This single-lip grease seal matches the following common seal numbers:
| Brand | Part Number |
|---|---|
| Chicago Rawhide/SKF | 17617 |
| Dexter | -- |
| Lippert | -- |
| National/Timken | 204002 |
| NOK | AF8057E0 |
| Transcom | 17273VHY |
Use a digital caliper and measure to the nearest thousandth of an inch.
Measure each location in a few spots to check for wear or an out-of-round surface. Match both measurements to the replacement seal.

Today were going to review part #SL175. This is a Redline Grease Seal. This is a single lip seal design, and it is designed to be used on an agricultural hub. The dimensions on this: The overall diameter is 2.722. The internal or inside diameter of the seal is 1.750. Now, if you go to the product page for this part number, on that page we will list a seal cross-reference chart, and that chart will list the different brands of seals that are out there.
It will also list the part number for that brand. If you have a part number off this grease seal you need, you can just match it up, and if it shows on that chart, that means it would match this grease seal part number. That should do it for review on part #SL175. .

These seals fit a little loose, but given the unknown brandsize of the hubs, I rolled with them. After several thousand miles, they are holding up very nicely. There are no leaks, they are still in place, and they have not allowed any ingress of water or dirt.
