Question:
Does this match a seal with 171255 markings, picture attached?
asked by: Aaron
Expert Reply:
The seal we offer part # RG06-050 that you mentioned cross references as the same thing as a Transcom part 171255TB.
It would be the exact same as what you have/need.

If you’re not sure if a seal fits, take the seal and check it in the end of the hub if it just looks like it just barely larger then it should fit then you check the rubber side of the seal on the spindle housing and if it fits snuggly, it’s the right seal simple

These seals work great they have the double lips. I bought other seals by mistake and when I used the Easy-Lube bearing grease system, the single lip seals leaked grease all over the Brakes, then I had to buy a set of shoes.

They work great. I use them on my tow dolly and change them once a year or whenever I repack my bearing, usually annualy.
