Replacement Grease Seal for a 168255TC Rubber Coated Seal  


I need to replace the inner seal on my boat trailer. The old sea number is 168255TC. It has rubber all around the metal case. Do you have this or an adequate substute part?


Expert Reply:

We do have a compatible grease seal for your 168255TC oil seal, however, we do not carry rubber coated seals in this size. The 168255TC oil seal was designed to work with oil bath hubs on a 3,500 lb axle. For the most part, axle manufacturers have stopped making 3,500 lb axles with oil bath hubs because grease has been more reliable.

Instead, I would recommend using the double lip grease seal, # 168255TB, and converting the hub to grease. This seal has the same inner diameter as your seal of 1.687 inches and will fit the same size hub bore of 2.561 inches. At this time we do not carry an oil seal in this size.

The outer diameter of your 168255TC seal is 2.568 inches because of the additional rubber coating and the outer diameter of the 168255TB seal is 2.565 inches. Both seals will still fit in the same size hub bore and on the same size spindle.
