Features:
Seal numbers are not always listed the same way across axle and hub brands, so the cross-reference data gives you another way to confirm the replacement before the hub comes apart. This unitized oil seal matches the following common seal numbers:
| Brand | Part Number |
|---|---|
| Chicago Rawhide/SKF | 27438, CR27438 |
| Dexter | 010-257-00, K71-865-00 |
| Lippert | -- |
| National/Timken | 370352A |
| NOK | -- |
| Transcom | -- |
Use a digital caliper and measure to the nearest thousandth of an inch.
Measure each location in a few spots to check for wear or an out-of-round surface. Match both measurements to the replacement seal.

Fast shipping and fit perfect
I repair trailers, these seals work good every time
The product was excellent and service is excellent
Good source for trailer parts and prompt shipping
Product was exactly what I needed to get back on the road. The picture zoom assured me that the part that I was getting matched to old one exactly. The product also arrived in a timely manner. To top it all off the customer service, attention, and follow up have been second to none.
Good service and fast shipping!
We did receive our order yesterday afternoon. I was not happy to see how the packing was done and did take a picture of the box when I opened it. All Bearing and Seals was thrown in the box and not protected during shipping. Now I'm second guessing if the bearing are damaged from shipping. They was not wrapped and my concern would be if the bearing was nicked or scratched during shipping . I would appreciate a contact in regards to this matter .
Sheila was the best! She knows her stuff and got me all the right part numbers and items for a 10,000# double axle brake rebuild. Brakes, bearings, races, seals etc. Shipping was quick and the couple B/O items shipped a few days later as she indicated. Now all I have to do it is put it all back together.
Great product and fast service. I will be back I have other trailers and I have told several or maybe even many people about you. Thank you so much These were mostly bearings and seals for a heavy trailer so I don't have any pictures. Take my word for it though with them
Being on the trailer repair business I replace a lot of axle seals - and a n alarming amount of failed ones. It doesn't pay to go cheap. These hub oil seals by Redline seem to be good quality and hold up well.
One seal did not want to fit. Could not get any help or a call back from etrailer. Very dissatisfied.
no more leaky axle seals with these.
I am well pleased with the bearing seals, they were a bit expensive but needed, only criticism is the packaging for shipment. I spent $240 on seals and needed them on a tight timeline, they were shipped in a light weight bubble wrap envelope, They made it okay but I really would have appreciated more care in pscking to ensure they are not damaged and having to go through a return process.
Correct seal that fits well!
Fantastic customer service.
excellent service got the parts I needed and very quickly
no leaks so far!! fit perfectly.
Just be careful during installation to not bend them, since they rotate inside of each other.
Info for this part was:

these seals seem to have stopped all internal oil leaks to my brake shoes.
