Question:

Good morning I have a client who is in need of a replacement seal for their RV. The seal they are replacing is a Trostel 300-156-6, I am having trouble finding an appropriate replacement. Do you offer any products that would fit? Regards, Jacob S.

So after quite a bit of research it seems that the Trostel 300-156-6 seals you mentioned are quite old and have not been around for some time. The best I could find was that they are 3.00" in outer diameter, and I did manage to find a customer who left a review saying a good replacement was the Grease Seal # 29031.

You can see that in the accompanying cut out I added, and though I can't verify that for certain, you may be able to if it is possible to measure the spindle where the grease seal rides (or better yet the seal itself). This seal measures 3.00" outer diameter, 1.875" inner diameter, and 0.508" tall.

Using those dimensions you would be able to verify the fit of the Grease Seal # 29031.
