Today were going to review part #21325. This is a Redline Grease Seal. This is a double lip grease seal, and it is designed to be used with Unique #42 hubs. Does have an outside diameter of 3.269. Has an inner diameter of 2.125. If youll go to the product page for this part number, we will have a chart, which is a seal cross-reference chart, and it will list the part numbers for other grease seal manufacturers for their part number that would match this grease seal part number.
That should do it for review on part #21325. .

Not only did they have a rare seal, they had it in the mail and at my house the next day. Thanks Renee for getting me on the road on time!
I purchased this product after I had made an error by reading on the same page that 21325 "VS" seal #10-36 were the same and was two for the price of one so I purchased the wrong one. And after I recieved it found out it was the wrong part. Not your fault I guess I was misled by my own greed thinking that I was saving money. I should have been more careful and checked the dimensions better. But you sent this new product 21325 to me very fast and that did please me very much.
Thank You-----H. Vinson
Good Quality products, fast service .. had a small part wrinkle but Noah took the extra time to actually help me (twice) to make sure I had what I needed.
The type of service you expect but rarely get!
You had the right part at a good price and I received then quickly. The seals are working great. Think you having the right seal at a good price.
Was exactly as indicated. Easy to search for.
Great service fast delivery will definitely use e trailer again Thanks
Super fast shipping, these are twice as thick I think a better fit for these hubs. Seat depth wise
Fits well, does the job, reasonably priced. What more can you ask for? Thanks etrailer for excellent service again.
Didn't fit our trailer, but seals appeared decent quality
Works perfect...Etrailer was great help in finding the right parts.
Everything good, etrailer is a great source for our fleet needs
Service from etrailer.com is excellent. Parts were same as OEM.
I ordered these seals after checking every parts store and rv store around nobody had them. I ordered online and the seal is exactly what I needed. Price was right Shipping was fast.
These fit my application like a glove !!! Way easier than piecing together all the parts separately!! Hardest part of the install was re-starting the brake line fitting because it fit so perfectly to my application !!
Etrailer was the only company that could match up part numbers that i had and was the right part and I got the parts fast
This seal was a exact replacement for the seal I replaced. None of the auto stores could find this. Thanks etrailer for still stocking this older hard to find grease seal. I was back on the road with my trailer (6 lug hub) in nothing flat.
I needed an oddball part for a fifty year old trailer and Sara found it nearly instantly. That is perfection!!

Sara to the rescue! I will make sure she sees your review! Thanks so much :)
When our local auto parts store couldn't match our bearings seals, and in fact ordered in the wrong seal based on the dimensions he took from the old seal, we turned to the internet and found etrailer.com. Etrailer.com had the correct seal at a price that was WAY below the incorrect seals we were originally sold. Even when we factored in the shipping we still paid half of what we were sold across the counter.
Thank you etrailer!
This seal worked perfect.
Seems to be an Odd size. Was very difficult to find this seal. Thanks etrailer!!
This seal fit my 1984 ezloader trailer hubs with a seal OD surface dimension of approximately 3.260"
Thanks again, and Ill look to etrailer first next time I need a part for my trailer.
Seals worked good on an old mobile home axle I had. Used it on the framework for my homemade band saw mill so I could move it into position to use.
I had the hardest time finding this particular size bearing and seal. Couldn’t find it any any local auto shops or many places online. E trailers was the only place I could find it, and it fit perfectly.
I live in a location where I only drive 5 miles back and forth to the ramp. All gravel roads. Freezes in the winter, so only use the boat May- September. For those 5 months the new bearing and seal work great.
Very informative web page, and helpful customer review blog. You can find almost any trailer question you may have. These hard to find grease seals were readily available and fit perfect. I used them for my 1986 boat trailer conversion project.
I appreciate the fast shipping!
These grease seals were hard to find, but etrailer had them in stock. They fit a 1979 EZ Loader boat trailer with twin 6 lug axles. My vintage boat trailer uses the typical 5200# wheel bearings, but uses a smaller O.D. grease seal than most similar boat trailers.
Chris was a huge help when I ordered these. I told him we have some pretty solid trailer parts suppliers in town, but they all struck out on this. He made sure I got the correct parts. I’ve already installed them, and it seems to be a proper fit.
Info for this part was:
At etrailer we provide the best information available about the products we sell. We take the quality of our information seriously so that you can get the right part the first time.
