The white seals now are made of nylon with a white graphite coating. They will NOT absorb oil and soaking could remove the graphite coating.

He said to press them in the grove and trim if necessary. Then lightly coat the exposed surface with Lubriplate No. 105 Motor Assembly Grease.

Thanks for sharing,thats good information. Just about all of the seals I have used have been the old ones but I do have some of those new ones mentioned here.
