Replacement Double Lip Seal for Boat Trailer with 473317 Seals

Question

Question:

I need double lip wheel bearing seals for my boat trailer. I have used NOK AD2527E and National 473317 in the past. I do have Bearing Buddys. The bearing numbers are L68149 and L44649. I do want a premium seal. What seal number should I purchase from your company? Do you have a Bearing Buddy brand seal available? Thank You

Helpful Expert Reply:

You would want to go with a double lip seal since your trailer is a boat trailer that will be submerged underwater. For that you would want the part # 168233 which is a double lip seal in the exact dimensions as you would need.

We don't have a Bearing Buddy brand seal but this one will work well for you.
