We have the Dexter Axle Double Lip Seal for Marine Hubs # 168255TB which has the 1.68 inch diameter you need along with the 2.56 inch inside hub diameter you need.

I didn’t notice that my original hub seals for my Dexter 3700# axles were 2.56 OD x 1.68 ID, and had ordered the complete Kodiak XL Pro hub, caliper, etc. kit. The kit came with 2.56 OD X 1.72 ID inner seals. After installation, they are leaking on the back side. My fault for not checking, but wondering if I install these seals, should that fix the leak. They are the oil bath types, so I want to make sure these seals are compatible with the oil hubs. I did all 4 hubs, and they all leak. Assistance would be appreciated. Thank you.

@Darren You need an oil seal and not a grease seal. A grease seal might work for a little bit but a grease seal does not need to seal as tight as an oil seal.

@JamesonC thank you. I will have to order the 168255TC so that it has the diameters I need, and is for oil bath bearings. 2.56OD and 1.68ID. It is what was in the old hub/rotors I had, and never leaked. Thank you.
