Expert Reply:

I have three seals with the 2.125 inner diameter. The Grease Seal, item # 21325, the Grease / Oil Seals 10-10 (Pair) - Double Lip Seals, item # RG06-090 and the Grease Seal GS-2125DL.

The # 21325 grease seal has an outer diameter of 3.269 inches and is .50 inches thick. This is the only seal I stock with a 3.269 outer diameter.

The # GS-2125DL and the # 10-10 grease seal have a outer diameter of 3.376 and are .31 and .430 inches thick respectively. These seals are viewed as interchangeable and the double lip seal is used for trailers with ez-lube spindles, bearing protectors, or oil bath bearings.

I do not have a cross reference for the part number that you have listed. If the above seals do not work for you let me know the inner and outer bearing numbers. With those part numbers I can cross reference the hub and spindle dimensions for your trailer and can make a recommendation for the correct seal you need to use.
